Index matching two sensors' pixels (Suomi-NPP)

SNPP CrIS-VIIRS 750-m Matchup Indexes V1 (SNPP_CrIS_VIIRS750m_IND) at GES_DISC
atmosphere NASA GES_DISC Level 2
In plain English

What it measures. A lookup table that links the pixels of one Suomi-NPP sensor to the matching pixels of another, so measurements from the two instruments can be lined up over the same spot.

How it's made. Generated as a collocation index for the Suomi-NPP satellite as part of a long-term water-vapor, temperature, and cloud data record project.

How & where you'd use it. A behind-the-scenes tool for researchers who want to combine readings from the two sensors; it is not a measurement of the Earth itself but a way to pair other datasets.

Official description

This dataset includes SNPP VIIRS-CrIS collocation index product, within the framework of the Multidecadal Satellite Record of Water Vapor, Temperature, and Clouds (PI: Eric Fetzer) funded by NASA’s Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, 2017. The dataset is built upon work by Wang et al. (doi: 10.3390/rs8010076) and Yue (doi:10.5194/amt-15-2099-2022). The short name for this collections is SNPP_CrIS_VIIRS750m_IND
