Terra MODIS Version 6 Land Surface Temperature/Emissivity - Data Retrieval Alert

The Land Data Operational Product Evaluation (LDOPE) team discovered a performance issue for the Terra MODIS Version 6 (V6) Daily Land Surface Temperature/Emissivity (LST&E) data products. Valid pixel counts for daily mid-latitude V6 Level-2 and Level-3 LST&E data show a significant loss of valid retrievals compared to V6.1. The loss of data retrieval was traced to the Terra photovoltaic (PV) long-wave infrared (LWIR) cross-talk issue and a correction was implemented into the V6.1 processing. Users are encouraged to switch to the V6.1 LST&E data products.

• MODIS/Terra Land Surface Temperature/Emissivity 5-Min L2 Swath 1km V006 - MOD11_L2
• MODIS/Terra Land Surface Temperature/Emissivity Daily L3 Global 1km SIN Grid V006 - MOD11A1
• MODIS/Terra Land Surface Temperature/Emissivity 8-Day L3 Global 1km SIN Grid V006 - MOD11A2
• MODIS/Terra Land Surface Temperature/Emissivity Daily L3 Global 6km SIN Grid V006 - MOD11B1
• MODIS/Terra Land Surface Temperature/Emissivity 8-day L3 Global 6km SIN Grid V006 - MOD11B2
• MODIS/Terra Land Surface Temperature/Emissivity Monthly L3 Global 6km SIN Grid V006 - MOD11B3
• MODIS/Terra Land Surface Temperature/Emissivity Daily L3 Global 0.05Deg CMG V006 - MOD11C1
• MODIS/Terra Land Surface Temperature/Emissivity 8-Day L3 Global 0.05Deg CMG V006 - MOD11C2
• MODIS/Terra Land Surface Temperature/Emissivity Monthly L3 Global 0.05Deg CMG V006 - MOD11C3

The main impact is to the MOD11_L2, MOD11A1, and MOD11B1 V6 data products. It then carries through all downstream V6 LST&E data products.
