MODIS/Terra Net Evapotranspiration Yearly L4 Global 500m SIN Grid V006

Yearly composite data for global evapotranspiration and latent heat flux at 500-meter resolution, produced by NASA. The product is based on the Penman-Monteith equation using MODIS remote sensing and meteorological reanalysis data. This version (V006) has been decommissioned due to input data errors; users are directed to the MOD16A3GF Version 6.1 product.

Use Cases

• Modeling global water cycles based on yearly evapotranspiration (ET) and latent heat flux (LE) layers.
• Assessing vegetation water use and drought impacts based on potential ET (PET) and potential LE (PLE) data.
• Analyzing long-term land surface energy balance based on the algorithm's integration of MODIS vegetation, albedo, and land cover data.

Strengths

• Spatial resolution increased to 500 meters from 1,000 meters in the previous version.
• Provides multiple layers including yearly ET, LE, PET, PLE, and a quality control layer.
• Algorithm incorporates daily meteorological reanalysis and MODIS remote sensing products.

Limitations

• This specific version (V006) is decommissioned due to unexpected errors in the input data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
