Therefore, this section provides such information in a timely manner (in specific coordinates). We recommend reading the post new daily daily weather data for crop growth simulations.

In the picture below (1) the coordinates can be obtained by clicking on the map. Should you specify (2) the parameters to generate the query, if everything is correct, with the Excute (3) button is activated to send the query.
