Samples are analyzed for ions including hydrogen (pH), ammonium, calcium, sulfate, nitrate, chloride, and orthophosphate.
MYD16A2 Version 6.1 provides global 500-meter resolution estimates of evapotranspiration and latent heat flux as 8-day composites. The dataset is produced by LPCLOUD using an algorithm based on the Penman-Monteith equation, incorporating MODIS remote sensing data and meteorological reanalysis. Each composite period sums evapotranspiration values and averages latent heat flux values over eight days.
