LEOLSTCMG30: Monthly Global Land Surface Temperature Grids

Global monthly Land Surface Temperature (LST) data is derived from Low Earth Orbit satellite records of MODIS and VIIRS instruments. The product provides LST and error estimates for day and night, regridded onto 0.25, 0.5, and 1-degree climate modeling grids. A low-resolution RGB browse image in PNG format is also available.

Use Cases

• Climate model validation based on satellite-derived land surface temperature grids.
• Trend analysis of global land surface temperature using monthly time-series data.
• Uncertainty quantification in thermal remote sensing based on per-pixel error estimates.
• Visualization of thermal patterns using the provided low-resolution RGB browse images.

Strengths

• Provides well-characterized per-pixel uncertainties for both day and night LST.
• Available at multiple spatial resolutions (0.25°, 0.5°, 1°) optimized for climate modeling.
• Version 2 corrected an issue where nighttime LST error estimates were erroneously filled with zero values.

Limitations

• Column names and specific data structure are not provided in any source description.
• The exact temporal coverage and total row count are unknown.
• License is specified only as 'other-license-specified', requiring further investigation.
