| Description |
MODAPS is currently set to reprocess all C61 L1B, Atmosphere, and the Land LST MYD21 product suite, for the period 2022-04-17 (DOY 2022-107) thru 2022-07-26 (DOY 2022-207 included). This reprocessing will address the drift in the cross-talk correction for the PV-LWIR bands 27-30 that was noticed after the Aqua MODIS instrument came back from the last S/C and instrument safe-mode that lasted between 2022-03-31 (DOY 090) and 2022-04-14 (DOY 104). More details regarding this last safe-mode and the progression of events following that can be found (here. The same L1B LUTs that resolves this drift in the PV-LWIR cross-talk, have been operational in the C61 forward processing stream, starting DOY 2022-208 (2022-07-27). The main impact from this cross-talk update is expected to be on the cloud and water vapor Atmosphere products. The MYD21 LST product is also expected to show differences of up to 0.5-1K, mainly over the vegetated areas. Users are requested to take note of this and start using the reprocessed versions of these products for any future studies. |
