TRANSITIONED PRODUCT DETAILS
Convective Percent
Operationally the official AMSR-E convective percent product (Adler et al., 2007) is transitioned to SPoRT's NWS partners. This product is obtained in near real-time from NESDIS and sent to the NWS. Convective percent of precipitation ranges from 0 (completely stratiform) to 100 (completely convective). This product has an approximate 5 km surface resolution. Occasionally this product is contaminated near coastlines and sea ice, and algorithm filters are used to mask nearly all of this contamination. This product has applications in determining rain type as well as giving an estimation of cloud type. Additional information can be found at the National Snow and Ice Data Center DAAC site.

Rain Rate
Operationally the official AMSR-E rain rate (Adler et al., 2007) is transitioned to SPoRT's NWS partners. This product is obtained in near real-time from NESDIS and sent to the NWS. Rain rate is an instantaneous estimate valid from 0-50 mm/hr. The product has an approximate 5 km surface resolution. Occasionally this product is contaminated near coastlines and sea ice, and algorithm filters are used to mask nearly all of this contamination. This product has applications in estimating rainfall rates over regions that are not measured by land-based Doppler radars. Additional information can be found at the National Snow and Ice Data Center DAAC site.
TRANSITIONED PRODUCT DETAILS
Sea Surface Temperature
AMSR-E sea surface temperature (Wentz and Meissner, 2004) is transitioned to SPoRT's NWS partners. This product is obtained in near real-time from NESDIS and sent to the NWS. The sea surface temperature product is an estimate valid from -3 to 34.5°C. The product is available at 56- and 38-km resolutions. Additional information can be found at the National Snow and Ice Data Center DAAC site.
TRANSITIONED PRODUCT DETAILS
Total Precipitable Water
Operationally the official AMSR-E water vapor (Wentz and Meissner, 2004) is transitioned to SPoRT's NWS partners. This product is obtained in near real-time from NESDIS and sent to the NWS. The water vapor product is an estimate valid from 0 to 75 mm. The product is available at 21-km resolution. Additional information can be found at the National Snow and Ice Data Center DAAC site.
TRANSITIONED PRODUCT DETAILS
Wind Speed
Operationally the official AMSR-E wind speed (Wentz and Meissner, 2004) is transitioned to SPoRT's NWS partners. This product is obtained in near real-time from NESDIS and sent to the NWS. The wind speed product is an estimate valid from 0 to 50 m/s. The product is available at 21- and 38-km resolutions. Additional information can be found at the National Snow and Ice Data Center DAAC site.
RESEARCH PRODUCT DETAILS
Cloud Liquid Water
AMSR-E cloud liquid water (Wentz and Meissner, 2004) is a SPoRT research product being evaluated for transition using data in near real-time from NESDIS. Cloud liquid water is a measure of the amount of in-cloud liquid within an atmospheric column. The cloud liquid water product is an estimate valid from 0 to 3 mm over ocean only. The product is available at 12-km resolution. Cloud liquid water is helpful for determining the location of clouds and can be used as a proxy for precipitation amount (with larger cloud liquid water leading to potentially heavier precipitation). Additional information can be found at the National Snow and Ice Data Center DAAC site.
RESEARCH PRODUCT DETAILS
Snow Water Equivalent
The official AMSR-E snow water equivalent (Kelly et al., 2004) is a SPoRT research product being evaluated for transition using data in near real-time from NESDIS. Snow water equivalent (SWE) is an instantaneous estimate valid from 0-480 mm. SWE is estimated for each cell using the snow depth and the ancillary snow density data during daytime only. The spatial resolution of the original data is 25x25 km. It has been remapped to Lambert projection. The quality flags are not yet included here, and the navigational anomalies in the displayed images are being investigated. Additional information can be found at the National Snow and Ice Data Center DAAC site.
RESEARCH PRODUCT DETAILS
Soil Moisture
The official AMSR-E soil moisture (Njoku 2004) is a SPoRT research product being evaluated for transition using data in near real-time from NESDIS. Soil moisture is an instantaneous estimate valid from 0-0.5 g/cm3. The spatial resolution of the original data is 25x25 km. It has been remapped to Lambert projection. The quality flags are not yet included here, and the navigational anomalies in the displayed images are being investigated. Additional information can be found at the National Snow and Ice Data Center DAAC site.
RESEARCH PRODUCT DETAILS
Vegetation Water Content
The official AMSR-E vegetation water content (Njoku 2004) is a SPoRT research product being evaluated for transition using near real-time data from NESDIS. Vegetation-water content is an instantaneous estimate valid from 0-10 kg/m2. The spatial resolution of the original data is 25x25 km. Here it has been remapped to Lambert projection. The quality flags are not yet included here, and the navigational anomalies in the displayed images are being investigated. Additional information can be found at the National Snow and Ice Data Center DAAC site.
