**8.6. Development of digital agro-climatic atlas for improved crop planning**

The improved crop planning provides economic security to farmers. The improvement in crop planning for 'smart agriculture' depends on knowledge or information base from systematic historical data records on several agro-climatic databases valid for 127 agro-climatic regions. The long-term databases on satellite-based surface insolation, near-surface Tmax, Tmin, RHmax, RHmin, rainfall, LST, NDVI, ET<sup>0</sup> , AET, surface and root-zone soil moisture on monthly, seasonal and annual scales are generated after bias correction and temporal filtering at 5–10 km. The ancillary databases on soil physical and chemical properties are superimposed. Geospatial analysis can be carried out to bring out national-scale digital agro-climatic atlas.
