We have adapted the MODIS Observation Coverage (Obscov) algorithm to the gridding of the AIRS L1b calibrated brightness temperatures, and developed a “Numeric-Obscov” implementation capable of utilizing the AIRS Tophat PSF dataset [1, 2]. We show that Obscov significantly reduces AIRS gridded-artifacts from a day to a season over winter 2005. The Obscov algorithm provides a physically accurate gridding...
Aqua provides a direct measurement of the surface infrared radiation for a near decade (2003–2011) from a single satellite platform with two completely independent instruments (AIRS and MODIS). We produced a 0.5°×1.0° lat-lon daily gridded near fundamental decadal data record (FDDR) of AIRS all sky brightness temperatures (BT) for all 2378 AIRS channels including the 4µ and 12µ surface windows for...
