MSU Ch 4 Daily Lower Stratosphere Temps with Limb93 Correction L3 1 day 2.5 degree x 2.5 degree V001 (MSULST)

The Microwave Sounding Unit (MSU) Lower Stratosphere Deep Layer Mean Temperature product (MSULST) provides gridded lower stratospheric temperatures for each day derived from MSU instruments on several different platforms. The temperatures are derived from MSU channel 4 using the method of Spencer and Christy (1990) with the LIMB 93 limb correction based on latitude, longitude, month, and scan angle. The MSU instruments measure the thermal emission of radiation by molecular oxygen at four frequencies near 60 GHz. North (south) of 66.7N (S) the footprint data are assigned to grid boxes in a weighted method depending on footprint latitude. Horizontal averaging is used to fill some of the empty grid boxes.
