Water productivity mapping using Landsat 8 satellite together with weather stations.

The main goal of this research was to determine the spatial-temporal agro-ecological indicators of water productivity in watersheds with diferent types of land use and occupation, using Landsat 8 images, agro-meteorological stations and application of Monteithand SAFER (Simple Algorithm for Retrievi...

Descrição
Resumo:The main goal of this research was to determine the spatial-temporal agro-ecological indicators of water productivity in watersheds with diferent types of land use and occupation, using Landsat 8 images, agro-meteorological stations and application of Monteithand SAFER (Simple Algorithm for Retrieving Evapotranspiration) models to estimate the production biomass (BIO) and the actual evapotranspiration (ET), respectively. Incident global solar radiation (RS↓) is observed seasonality of radiation during the year.
