Which MODIS product contains Actual Evapotranspiration?

The MODIS product that contains information about actual evapotranspiration is MOD16.

MOD16 provides estimates of actual evapotranspiration (ET) at a 1 km spatial resolution on an 8-day interval. It calculates ET using a combination of MODIS land surface temperature (LST), normalized difference vegetation index (NDVI), and meteorological data. This product is widely used for monitoring water use, drought assessment, and understanding ecosystem dynamics.

The MOD16 product suite includes several datasets, each serving a specific purpose. Here's an overview of the commonly used MOD16 datasets:

  • MOD16A2: This dataset provides actual evapotranspiration (ET) estimates at a spatial resolution of 1 km and a temporal resolution of 8 days. It is derived from MODIS data and meteorological data using the Penman-Monteith equation.
  • MOD16A3: This dataset offers ET products at a global scale, providing aggregated monthly ET estimates derived from MOD16A2 data. It is useful for studying long-term trends and patterns in ET.
  • MOD16A4: Similar to MOD16A3, this dataset provides aggregated annual ET estimates derived from MOD16A2 data. It allows for the analysis of ET over longer time periods, such as multi-year trends or interannual variability.

These MOD16 datasets are widely used in hydrological modeling, water resource management, agricultural monitoring, and ecosystem studies to understand the spatiotemporal patterns of actual evapotranspiration across different regions of the Earth.
