Hyperspectral Infrared Atmospheric Sounder-II (HIRAS-II)
Description
HIRAS-II is the second generation of Hyperspectral Infrared Atmospheric Sounder (HIRAS).
Compared to HIRAS-I, HIRAS-II has firstly expanded to thermal infrared bands with more than 3,000 channels, has a finer spatial resolution from 16km to 14km, more than two times better sensitivity and significantly improved calibration accuracy.
