The first Moderate Resolution Imaging Spectroradiometer (MODIS) instrument is planned for launch by NASA in 1998. This will provide a new and improved capability terrestrial satellite remote sensing aimed at meeting the needs of global change research. MODIS standard products tools moderate resolution land surface monitoring. These higher order data have been designed to remove burden certain common types processing from user community meet more general global-to-regional monitoring,...
A suite of Moderate-Resolution Imaging Spectroradiometer (MODIS) snow products at various spatial and temporal resolutions from the Terra satellite has been available since February 2000. Standard include daily 8-day composite 500 m resolution swath tile (which fractional cover (FSC) albedo), 0·05° on a climate-modelling grid (CMG) also FSC). These (from Collection 4 (C4) reprocessing) are mature most have validated to varying degrees order through National Snow Ice Data Center. The overall...
The accurate knowledge of soil moisture and snow conditions is important for the skillful characterization agricultural hydrologic droughts, which are defined as deficits streamflow, respectively. This article examines influence remotely sensed depth retrievals toward improving estimates drought through data assimilation. Soil from a variety sensors (primarily passive microwave based) assimilated separately into Noah land surface model period 1979–2011 over continental United States, in...
[1] The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument was launched in October 2011 as part of the Suomi National Polar-Orbiting Partnership (S-NPP). VIIRS designed to improve upon capabilities operational Advanced Very High Resolution and provide observation continuity with NASA's Earth Observing System's Moderate Spectroradiometer (MODIS). Since first-light images were received November 2011, NASA- NOAA-funded scientists have been working evaluate performance generate land...
This paper provides a review and summary status of the research underway by NASA Terra Aqua Suomi-NPP Land Discipline Team to provide continuity global land data products from Moderate resolution Imaging Spectroradiometer (MODIS) Visible Infrared Radiometer Suite (VIIRS). The two MODIS instruments on Earth Observing System (morning overpass) (afternoon platforms have provided more than twenty years data. peer-reviewed generated are now being transitioned production using VIIRS inputs, with...
MODIS, the moderate resolution imaging spectroradiometer, will be launched in 1998 as part of first earth observing system (EOS) platform. Global maps land surface properties, including snow cover, created from MODIS imagery. The snow-cover mapping algorithm that used to produce daily global cover extent at 500 m is currently under development. With exception cloud largest limitation producing a product using presence forest canopy. A Landsat Thematic Mapper (TM) time-series southern Boreal...
Global sea ice products are produced from the Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) onboard both Terra and Aqua satellites. Daily extent surface temperature (IST) available at 1- 4-km resolution. Validation activities during "cold period" (when meltwater is generally not present) in Northern Hemisphere, defined here as October through May, have been undertaken to assess accuracy of 1-km resolution MODIS IST algorithm product. was also done South...
A joint US Air Force/National Aeronautics and Space Administration (NASA) blended global snow product that uses Earth Observation System Moderate Resolution Imaging Spectroradiometer (MODIS), Advanced Microwave Scanning Radiometer for the Observing (AMSR-E) Quick Scatterometer (QuikSCAT or QSCAT) data has been developed. Existing products derived from these sensors have into a single, global, daily, user-friendly by using newly developed Force Weather Agency (AFWA)/NASA Snow Algorithm...
Abstract. Knowledge of the distribution, extent, duration and timing snowmelt is critical for characterizing Earth's climate system its changes. As a result, snow cover one Global Climate Observing System (GCOS) essential variables (ECVs). Consistent, long-term datasets are needed to study interannual variability climatology. The NASA snow-cover generated from Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra Aqua spacecraft Suomi National Polar-orbiting Partnership (S-NPP)...
Abstract. MODerate resolution Imaging Spectroradiometer (MODIS) cryosphere products have been available since 2000 – following the 1999 launch of Terra MODIS and 2002 Aqua include global snow-cover extent (SCE) (swath, daily, 8 d composites) at 500 m ∼5 km spatial resolutions. These are used extensively in hydrological modeling climate studies. Reprocessing complete data record, from Collection 5 (C5) to 6 (C6) 6.1 (C6.1), has provided improvements product suite.

Abstract There are several hemispheric-scale satellite-derived snow-cover maps available, but none has been fully validated. For the period 23 October–25 December 2000, we compare snow of North America derived from Moderate Resolution Imaging Spectroradiometer (MODIS) and operational U.S. National Oceanic Atmospheric Administration (NOAA) Operational Hydrologic Remote Sensing Center (NOHRSC), both which rely on satellite data visible near-infrared parts spectrum; also MODIS with Defense...
Describes the snow mapping algorithm being developed for use with Earth Observing System (EOS) MODerate resolution Imaging Spectroradiometer (MODIS). A key component of this is normalized difference index (NDSI). The NDSI employs Landsat Thematic Mapper (TM) visible (0.56 /spl mu/m) and near-infrared (1.65 data. uses in combination reflectance to identify cover discriminate from clouds. NDSI-based functions a simple set decision rules snow, can be run an automated fashion on any TM scene...
An Earth Observing System global snow cover extent data products record at moderate spatial resolution (375–500 m) began in February 2000 with the Moderate-resolution Imaging Spectroradiometer (MODIS) instrument onboard Terra satellite. The continued Aqua MODIS July 2002, Suomi-National Polar Platform (S-NPP) Visible Infrared Radiometer Suite (VIIRS) January 2012 and continues Joint Satellite System-1 (JPSS-1) VIIRS, launched November of 2017. objective this work is to develop a Science Data...
