Campaign: Advanced Microwave Scanning Radiometer EOS on Aqua (AQUA_AMSRE)
The Advanced Microwave Scanning Radiometer Earth Observing System (AMSRE) was launched on May 4, 2002 aboard NASAs Aqua spacecraft. The National Space Development Agency of Japan (NASDA) provided AMSRE to NASA as an indispensable part of Aqua s global hydrology mission. Over the oceans, AMSRE is measuring a number of important geophysical parameters, including sea surface temperature (SST), wind speed, atmospheric water vapor, cloud water, and rain rate. A key feature of AMSRE is its capability to see through clouds, thereby providing an uninterrupted view of global SST and surface wind fields. The AMSRE Ocean Products produced here are made using a modified version of the ASMRE Direct Broadcast (DB) algorithm developed for NASA. An on orbit calibration method developed at Remote Sensing Systems (remss.com)is used to convert counts to brightness temperatures. Calibration methodology and preliminary validation results are described in the paper: ON ORBIT CALIBRATION OF AMSRE AND THE RETRIEVAL OF OCEAN PRODUCTS by Wentz et al. (http://ssmi.com/papers/amsr/on orbit_calibration_amsre_and_ocean_products.pdf). This project description is taken from: http://ssmi.com/amsr/amsr_data_description.html)

Source and Methods: the RSS AMSRE dataset consists of data derived from observations collected by the AMSRE instrument carried on board AQUA. L2P data products are derived from native SST data products. L2P data products consist of the original SST data values that have been reformatted to a netCDF file format. A L2P confidence data record is provided for each SST pixel. Remote Sensing Systems performs a detailed processing of AMSR-E instrument data in two stages.
The first stage produces a near-real-time (NRT) product which is made available ASAP, generally within 3 hours of when the data are recorded. The NRT products are not intended to be archive quality and are deleted within several days. "Final" data (identified by "v5" within the file name) are processed when we receive the NCEP FNL analysis. The NCEP wind directions are useful for retrieving more accurate SSTs and wind speeds. The final "v5" products will continue to accumulate new swaths (half orbits) until the maps are full, generally within 2 days. The final refers to the type of swath processing, and does not imply that a data file is finalized (as in, will not change). Calibration methodology and preliminary validation results are described in the paper: ON-ORBIT CALIBRATION OF AMSR-E AND THE RETRIEVAL OF OCEAN PRODUCTS by Wentz et al. (http://ssmi.com/papers/amsr/on-orbit_calibration_amsre_and_ocean_products.pdf). This project description is taken from: http://ssmi.com/amsr/amsr_data_description.html).

Description: sea_surface_temperature:
16-bit integer. AMSRE level 2 pre processed (L2P) SST. The Overall Quality Flag values may be used to filter out these unwanted values

wind_speed:
Wind speed measurements are required to derive L2P SST proximity confidence values, for use in diurnal variability correction schemes and to interpret the relationship between satellite and in situ SST data. At low wind speeds, especially in clear sky conditions, stronger diurnal variability is expected leading to higher surface layer temperature gradients and the potential for significant de-coupling of the skin/sub-skin SST from the SST at depth. Ideally a near contemporaneous wind speed measurement from satellite sensors should be used but this is impossible for all sensors due to the limited number of satellite wind speed sensors available. As a surrogate for a measured wind speed value, NWP estimates may be used as an indication of the surface wind speed.
