Theglobal ozone monitoring experiment (GOME):Mission concept and first scientific results

Burrows, JP; Weber, M; Buchwitz, M; et al.

Abstract:Theglobal Ozone Monitoring Experiment(GOME) is a new instrument aboard the European Space Agency’s (ESA)Second European Remote Sensing Satellite(ERS-2), which was launched in April1995. The main scientific objective of thegOME mission is to determine theglobal distribution of ozone and several other tracegases, which play an important role in the ozone chemistry of the earth's stratosphere and troposphere.gOME:measures the sunlight scattered from the earth's atmosphere and/or reflected by the surface in nadir viewing mode in the spectral region240-790 nm at a moderate spectral resolution of between 0.2 and 0.4 nm.Using the maximum960-km across-track swath width, the spatial resolution of agOMEground pixel is 40 ×320km2for the majority of the orbit andglobal coverage is achieved in three days after 43 orbits. Operational data products ofgOME asgenerated by DLR-DFD, thegerman Data Processing and Archiving Facility (D-PAF)forgOME, comprise absolute radiometrically calibrated earthshine radiance and solar irradiance spectra (level1 products) andglobal distributions of total column amounts of ozone and NO2, (level2 products), which are derived using the DOAS approach (Differential Optical Absorption Spectroscopy). (Under certain conditions and some restrictions, the operational data products are publically available from the European Space Agency via the ERS Helpdesk.) In addition to the operational data products,gOME has delivered important information about otherminor tracegases such as OClO, volcanic SO2,H2CO from biomass burning, and tropospheric BrO. Using an iterative optimal estimation retrieval scheme, ozone vertical profiles can be derived from the inversion of the UV/VIS spectra. This paper reports on thegOME instrument, its operation mode, and the retrieval techniques, the latter with particular emphasis on DOAS(total column retrieval) and advanced optimal estimation(ozone profile retrieval). Observation of ozone depletion in the recent polar spring seasons in both hemispheres are presented. OClO observed bygOME under twilight conditions provides valuable information on the chlorine activation inside the polar vortex, which is believed to be responsible for the rapid catalytic destruction of ozone.Episodes of enhanced BrO in the Arctic, most likely contained in the marine boundary layer, were observed in early and late spring. Excess tropospheric nitrogen dioxide and ozone have been observed during the recent Indonesian fire in fall1997. Formaldehyde could also clearly be identified bygOME and is known to be a by-product resulting from biomass burning.

The Moderate Resolution Imaging Spectroradiometer (MODIS): Land remote sensing forglobal change research

Justice, CO; Vermote, E; Townshend, JRG; et al.

Abstract:The first Moderate Resolution Imaging Spectroradiometer (MODIS) instrument is planned for launch by NASA in1998. This instrument will provide a new and improved capability for terrestrial satellite remote sensing aimed at meeting the needs ofglobal change research, The MODIS standard products will provide new and improved tools for moderate resolution land surface monitoring, These higher order data products have been designed to remove the burden of certain common types of data processing from the user community and meet the moregeneral needs ofglobal-to-regional monitoring,modeling, and assessment. The near-daily coverage of moderate resolution data from MODIS, coupled with the planned increase in high-resolution sampling from Landsat7, will provide a powerful combination of observations,The full potential of MODIS will be realized once a stable and well-calibrated time-series of multispectral data has been established. In this paper the proposed MODIS standard products for land applications are described along with the current plans for data quality assessment and product validation.

Satellite remote sensing of primary production

Tucker, CJ; Sellers, PJ

Abstract:Leaf structure and function are shown to result in distinctive variations in the absorption and reflection of solar radiation from plant canopies. The leaf properties that determine the radiation-interception characteristics of plant canopies are directly linked to photosynthesis,stomatal resistance and evapotran-spiration and can be inferred from measurements of reflected solar energy. The effects of off-nadir viewing and atmospheric constituents,coupled with the need to measure changing surface conditions, emphasize the need for multitemporal measurements of reflected radiation if primary production is to be estimated.

Aerosol properties over bright-reflecting source regions

Hsu, NC; Tsay, SC; King, MD; et al.

Abstract:Retrieving aerosol properties from satellite remote sensing over a bright surface is a challenging problem in the research of atmospheric and land applications. In this paper we propose a new approach to retrieve aerosol properties over surfaces such as arid,semiarid, and urban areas, where the surface reflectance is usually, very, bright in the red part of visible spectrum and in the near infrared, but is much darker in the blue spectral region (i.e., wavelength ＜ 500 nm). In order to infer atmospheric properties from these data, aglobal surface reflectance database of 0.1 degrees latitude by 0.1 degrees longitude resolution was constructed over bright surfaces for visible wavelengths using theminimum reflectivity, technique (e.g., finding the clearest scene during each season for agiven location). The aerosol optical thickness and aerosol type are then determined simultaneously in the algorithm using lookup tables to match the satellite observed spectral radiances. Examples of aerosol optical thickness derived using this algorithm over the Sahara Desert and Arabian Peninsula reveal various dust sources, which are important contributors to airborne dust transported over long distances.Comparisons of the satellite inferred aerosol optical thickness and the values fromground-based Aerosol Robotic Network (AERONET) sun/sky radiometer measurements indicategood agreement (i.e., within30%)over the sites in Nigeria and Saudi Arabia. This new algorithm, when applied to Moderate Resolution Imaging Spectroradiometer (MODIS), Sea-viewing Wide Field of view Sensor (SeaWiFS), andglobal Imager (GLI) satellite data, will provide high spatial resolution (similar to1km)global information of aerosol optical thickness over bright surfaces on a daily basis.

Objectively analyzed air-sea heat fluxes for theglobal ice-free oceans (1981-2005)

Yu, LS; Weller, RA

Abstract:A25-yr (1981–2005) time series of daily latent and sensible heat fluxes over theglobal ice-free oceans has been produced by synthesizing surface meteorology obtained from satellite remote sensing and atmospheric model reanalyses outputs. The project, named Objectively Analyzed Air–Sea Fluxes (OAFlux), was developed from an initial study of the Atlantic Ocean that demonstrated that such data synthesis improves daily flux estimates over the basin scale. This paper introduces the25-yr heat flux analysis and documents variability of theglobal ocean heat flux fields on seasonal, interannual, decadal, and longer time scales suggested by the new dataset. The study showed that, among all the climate signals investigated,the most striking is a long-term increase in latent heat flux that dominates the data record. Theglobally averaged latent heat flux increased by roughly9 W m-2between the low in1981 and the peak in2002, which amounted to about a10% increase in the mean value over the25-yr period. Positive linear trends appeared on aglobal scale,and were most significant over the tropical Indian and western Pacific warm pool and the boundary current regions. The increase in latent heat flux was in concert with the rise of sea surface temperature, suggesting a response of the atmosphere to oceanic forcing.

Satellite remote sensing of total herbaceous biomass production in the Senegalese Sahel:1980–1984

Tucker, CJ; Vanpraet, CL; Sharman, MJ; et al.

Abstract:NOAA-6 and NOAA-71-km and 4-km advanced very high resolution radiometer data were obtained at frequent intervals during the1980,1981,1982,1983, and1984 rainy orgrowing seasons in the Sahel zone of northern Senegal. Above-ground herbaceous biomass clippings, visual estimates, and hand-held radiometer measurements of herbaceous vegetation were made during and at the conclusion of the rainy seasons for 4 of the 5 years. The satellite data were compared to sampled aboveground biomass data and the integral of the satellite data over time was compared to end-of-growing-season aboveground total dry biomass. A strong correlation between the integrated NOAA-7 satellite data and end-of-season aboveground dry biomass was found forground samples collected over a3-year period. The satellite data documented the highly variable precipitation regime in the Senegalese Sahel both within years and among years and suggest a direct method of monitoring Sahelian total herbaceous biomass production in areas where the percentage cover of woody species is less than10%.Predicted average total dry biomass production was1093 kg/ha for1981, 536 kg/ha for1982,178 kg/ha in1983,and 55 kg/ha in1984 for the ～30000km2study area.

Evaluation of1D and2D numerical models for predicting river flood inundationHorritt, MS; Bates, PD

Abstract:1D and2D models of flood hydraulics(HEC-RAS, LISFLOOD-FP and TELEMAC-2D) are tested on a 60km reach of the river Severn, UK. Synoptic views of flood extent from radar remote sensing satellites have been acquired for flood events in1998 and2000. The three models are calibrated, using floodplain and channel friction as free parameters, against both the observed inundated area and records of downstream discharge. The predictive power of the models calibrated against inundation extent or discharge for one event can thus be measured using independent validation data for the second. The results show that for this reach both the HEC-RAS and TELEMAC-2D models can be calibrated against discharge or inundated area data andgivegood predictions of inundated area, whereas the LISFLOOD-FP needs to be calibrated against independent inundated area data to produce acceptable results. The different predictive performances of the models stem from their different responses to changes in friction parameterisation.

A local ensemble Kalman filter for atmospheric data assimilation

Ott, E; Hunt, BR; Szunyogh, I; et al.

Abstract:In this paper, we introduce a new. local formulation of the ensemble Kalman filter approach for atmospheric data assimilation. Our scheme is based on the hypothesis that, when the Earth’s surface is divided up into local regions of moderate size. vectors of the forecast uncertainties in such regions tend to lie in a subspace of much lower dimension than that of the full atmospheric state vector of such a region. Ensemble Kalman filters, ingeneral, take the analysis resulting from the data assimilation to lie in the same subspace as the expected forecast error. Under our hypothesis the dimension of the subspace corresponding to local regions is low. This is used in our scheme to allow operations only on relatively low-dimensional matrices. The data assimilation analysis is performed locally in a manner allowing massively parallel computation to be exploited. The local analyses are then used to constructglobal states for advancement to the next forecast time. One advantage, which may take on more importance as ever-increasing amounts of remotely-sensed satellite data become available, is the favorable scaling of the computational cost of our method with increasing data size, as compared to other methods that assimilate data sequentially. The method, its potential advantages, properties, and implementation requirements are illustrated by numerical experiments on the Lorenz-96 model. It is found that accurate analysis can be achieved at a cost which is very modest compared to that of a fullglobal ensemble Kalman filter.

A new algorithm for surface deformation monitoring based on small baseline differential SAR interferograms

Berardino, P; Fornaro,g; Lanari, R; et al.

We present a new differential synthetic aperture radar (SAR) interferometry algorithm for monitoring the temporal evolution of surface deformations. The presented technique is based on an appropriate combination of differential interferograms produced by data pairs characterized by a small orbital separation (baseline) in order to limit the spatial decorrelation phenomena. The application of the singular value decomposition method allows us to easily “l(fā)ink” independent SAR acquisition datasets, separated by large baselines, thus increasing the observation temporal sampling rate. The availability of both spatial and temporal information in the processed data is used to identify and filter out atmospheric phase artifacts. We present results obtained on the data acquired from1992 to2000 by the European Remote Sensing satellites and relative to the Campi Flegrei caldera and to the city of Naples, Italy that demonstrate the capability of the proposed approach to follow the dynamics of the detected deformations.
