**5. Product generations from the ground observations using GIS**

In the context to the Indian agriculture, advisories have been given to farmers using weather information at the district level. Weather information and their departure from normal value at different temporal and spatial scales are useful for the preparation of agromet advisories. In view of that, daily, weekly, fortnightly, monthly and seasonal contours (**Figure 3**) are being generated utilising the realised weather observations for the parameter temperature (maximum temperature, minimum temperature and diurnal temperature variation), maximum and minimum relative humidity, cloud and wind speed. Synoptic observatory data received through Global Telecommunication System (GTS) are used to generate contours on a pan India mode. Weather information and their departure from normal value at different temporal and spatial scale is useful information for preparation of agromet advisories.
