MODIS/Terra Net Evapotranspiration 8-Day L4 Global 500m SIN Grid V061
The MOD16A2 Version 6.1 Evapotranspiration/Latent Heat Flux product is an 8-day composite dataset produced at 500 meter (m) pixel resolution. The algorithm used for the MOD16 data product collection is based on the logic of the Penman-Monteith equation, which includes inputs of daily meteorological reanalysis data along with Moderate Resolution Imaging Spectroradiometer (MODIS) remotely sensed data products such as vegetation property dynamics, albedo, and land cover. Provided in the MOD16A2 pro

Useful for
- Use cases llm-inferred
- Catchment water-balance inputs for flood risk assessment (FRA) and drainage strategy context · Regional evapotranspiration baseline for groundwater recharge or abstraction screening · Evapotranspiration context for ecological or BNG habitat water-use assessment
- Audience llm-inferred
- hydrologists · flood consultants · drainage engineers · ecologists · GIS analysts
Limitations
- Constraints llm-inferred
- 8-day composite, not daily; the final composite of each year is 5 or 6 days · 500 m pixels are too coarse for site-scale assessments · Access requires AWS credentials, so it is not a fully open download · Operational and uncertainty issues are documented in the User Guide Section 3 and the MODIS/VIIRS Land Quality Assessment site; check these before use · Uses climatology LAI/FPAR as a backup to operational LAI/FPAR
