The Afternoon Train, or 'A-Train', for short, is a constellation of satellites that travel one behind the other, along the same track, as they orbit Earth. Currently, the GPM Microwave Imager (GMI) is the reference instrument for calibrating the other sensors. Glory was lost in a launch vehicle failure on March 4, 2011. It lies between the super high frequency band and the far infrared band, the lower part of which is the terahertz band. Microwave-only products include CHOMPS and the SSM/I datasets; PERSIANN and CMORPH combine information from passive microwave and infrared. Four satellites currently fly in the A-Train - Aqua, CloudSat, CALIPSO, and Aura. Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). These data allow quantitative maps of precipitation across a swath that is 885 km (550 miles) wide. The 1C data product is the lowest level passive-microwave data product that most researchers are interested in examining, although some instruments have … GPM Microwave Imager (GMI) The GMI is a passive sensor that observes the microwave energy emitted by the Earth and atmosphere at 13 different frequency/polarization channels. GCOM-W1 and OCO-2 are scheduled to join the configuration in 2012 and 2013, respectively. NASA’s Earth Science Program is dedicated to advancing Earth remote sensing and pioneering the scientific use of satellite measurements to improve human understanding of our home planet in order to inform economic and policy decisions and improve operational services of … Climate-quality, gauge-based data sets can be difficult to construct due to the widely distributed …
