MODIS Terra Net Evapotranspiration Gap-Filled 8-Day L4 Global 500m
The MODIS Terra MOD16A2GF Version 6.1 product provides a gap-filled 8-day composite of Evapotranspiration (ET) and Latent Heat Flux (LE) at 500 m spatial resolution. The dataset is based on an algorithm derived from the Penman-Monteith equation, which integrates daily meteorological reanalysis data with MODIS-derived variables such as vegetation dynamics, albedo, and land cover. The gap-filled product is generated at the end of each year once the complete annual MOD15A2H LAI/FPAR dataset becomes

- Resolution docs-verified
- 500 m spatial; 8-day temporal composite
- Update frequency docs-verified
- Gap-filled product generated once per year, at year end, after the annual MOD15A2H LAI/FPAR dataset is complete
- Formats docs-verified

- Access docs-verified
- Licence 'other' (LP DAAC data citation and policies). Asset access is via Copernicus Data Space: HTTPS/Product assets use OIDC (CDSE identity) authentication; S3 assets use S3 credentials. CREODIAS S3 is requester-pays; CDSE S3 is not. No API key or price stated.
Useful for
- Use cases llm-inferred
- Regional evapotranspiration baseline for water-balance checks on FRA or drainage projects · Catchment ET inputs for hydrological or groundwater recharge modelling · Vegetation water-use context for BNG or habitat water-demand assessments
- Audience llm-inferred
- hydrologists · water resources engineers · drainage engineers · ecologists · GIS analysts
Limitations
- Constraints llm-inferred
- 500 m grid is too coarse for site-scale assessment · 8-day composites, not daily values · Gap-filled product is only generated annually, so the most recent periods may lack the gap-filled version (inferred from the annual generation cycle) · Licence is 'other' and requires checking LP DAAC policy before reuse · Downloads need CDSE OIDC or S3 credentials · HDF format needs conversion for most GIS and consultancy tools · Global extent, not UK-specific
