SNPP_CrIS_VIIRS750m_IND: Satellite Collocation Indexes

NASA's MEaSUREs program produced this dataset of collocation indexes for the Suomi NPP satellite's VIIRS and CrIS instruments. It supports the creation of a multidecadal record of water vapor, temperature, and clouds. The dataset is built upon published research by Wang et al. and Yue.

Use Cases

• Creating matched satellite data pairs for cross-instrument validation based on VIIRS-CrIS collocation indexes.
• Analyzing long-term trends in atmospheric water vapor and cloud properties using a multidecadal satellite record.
• Developing and validating algorithms for cloud detection and atmospheric profiling using collocated sensor data.

Strengths

• Part of NASA's MEaSUREs program, which aims to produce stable, long-term Earth System Data Records.
• Built upon peer-reviewed research with specific citations (Wang et al. 2016, Yue 2022).
• Available on multiple authoritative platforms (Data.gov, NASA Earthdata), indicating established use.

Limitations

• Key metadata like column names, row count, and exact file size are not provided on any platform.
• Conflicting last-update dates exist between sources (2026 vs. 2022), creating uncertainty about data freshness.
• License is ambiguously listed as 'other-license-specified' without further details.
