Description

The MYD16A2 Version 6.1 Evapotranspiration/Latent Heat Flux product is an 8-day composite product at 500 meter 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 MODIS remotely sensed data products such as vegetation property dynamics, albedo, and land cover.

The pixel values for the ET, LE, PET and PLE layers are the sum for all days within the 8-day composite period.Note that the last 8-day period of each year is a 5 or 6-day composite period, depending on the year.

The Version 6.1 Level-1B (L1B) products have been improved by undergoing various calibration changes that include: changes to the response-versus-scan angle (RVS) approach that affects reflectance bands for Aqua and Terra MODIS, corrections to adjust for the optical crosstalk in Terra MODIS infrared (IR) bands, and corrections to the Terra MODIS forward look-up table (LUT) update for the period 2012 - 2017. A polarization correction has been applied to the L1B Reflective Solar Bands (RSB). The product uses Climatology LAI/FPAR as back up to the operational LAI/FPAR.

According to the MODIS Science Team, The MYD16A2 6.1 product will not have data prior to 2021. The MODIS Science team recommends using the gap-filled MYD16A2GF 6.1 product for data from 2000 to 2021 -- and then also 2022 when the data are available. They recommend this as the gap-filled product is expected to be superior in product quality, especially over areas where otherwise the routine product performance would have been negatively impacted by cloudy or poor quality input observations. For the current year, there will not be a gap-filled product until early the following year (i.e. 2023 data should be available in early 2024). So, if a user needs MYD16A2GF 6.1 data for the year 2023 (or the "current" year in the future), they recommend using the MYD16A2 6.1 product, which is generated using the daily observation with climatology observation replacing for the cloudy or poor quality observations.
