Helper file matching two instruments' pixels (Aqua)
What it measures. Not an Earth measurement itself, but a lookup table that matches up pixels from two instruments on the same satellite, telling you which AIRS observation lines up with which 1-kilometer MODIS pixel.
How it's made. Generated as a collocation index for the Aqua satellite's AIRS and MODIS instruments, built as part of a long-term water vapor, temperature, and cloud data-records project.
How & where you'd use it. A helper file for researchers who need to combine AIRS and MODIS data accurately. It is used alongside those instruments' data rather than offering observations of its own.

Official description
This dataset includes Aqua AIRS to MODIS 1-km 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 Aqua_AIRS_MODIS1km_IND
