Ivanpah Playa Satellite Calibration Site Measurements

Ivanpah Playa is one of eight instrumented sites in the CEOS LANDNET network for vicarious calibration of Earth-observing satellites. The site provides surface and atmospheric measurements to support the intercomparison and traceable validation of wide-swath sensor data. Data for this US-managed site is provided by the USGS Long Term Archive.

Use Cases

• Predict Top of Atmosphere (TOA) radiance for wide swath sensors using site characteristics and instrument data.
• Intercompare radiometric gain biases between in-flight and future instruments using field campaign data from the site.
• Validate satellite-derived climate products using continuous surface and atmospheric measurements from the automated site.

Strengths

• Part of a network of eight CEOS Reference Test Sites for international harmonization.
• Three sites in the network can operate in a fully automated manner, providing continuous data.

Limitations

• The specific row count, column names, and temporal coverage for the Ivanpah Playa site are unknown.
• Data availability and update frequency are not specified in the provided description.
