3.2. Computing the ET0.
3.3. Preparation of a ten-daily rainfall and ET0 database for crop forecasting
4. Gathering and calculating crop data
4.1. Analysis of time series of climate and crops to identify trends. Construction of detrended crop yield time series.
4.2. Preparation of polygons for main crop growing areas in the country and define cropping practices and conditions.
5. Techniques to use when data are unavailable
5.1. Introduction to Geostatistics and the spatial interpolation of weather and crop data.
5.2. How to fill gaps in data records
6. The FAO water balance model and its crop forecasting indicators
