ECOSTRESS Swath Cloud Mask: Global 70m Resolution Land Surface Data

ECOSTRESS Swath Cloud Mask Instantaneous L2 Global 70 m V002 is a NASA data product derived from the ECOSTRESS instrument on the International Space Station. It provides a cloud mask layer to determine cloud cover for accurate land surface temperature and evapotranspiration estimation. The dataset has a 70-meter resolution and covers latitudes between 52° N and 52° S.

Use Cases

• Filtering cloud-contaminated pixels for land surface temperature analysis based on the cloud mask layers.
• Improving evapotranspiration estimation models by using the cloud mask to isolate clear-sky observations.
• Studying cloud cover patterns and their impact on surface energy balance within the instrument's latitudinal range.

Strengths

• Data is produced by NASA, an authoritative source for spaceborne earth science.
• Provides two specific cloud mask layers: 'Brightness temperature LUT test' and 'Final cloud mask'.
• Covers a specific and consistent latitudinal range between 52° N and 52° S.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes historical data acquisition gaps and instrument anomalies affecting some periods.
