How Do I Edit Precipitation Events?

Overview:

The Granular Crop Model uses weather data to calculate nitrogen levels and generate  nitrogen prescriptions. By default, this comes from IBM, and includes: 

• Precipitation
• Temperature (min, max)
• Solar radiation

We can customize the source of precipitation data by manually editing weather events. 

(To link a personal weather station from Weather Underground, see these instructions.)

Prerequisites:

• Grower created in Granular Insights.
• Permissions set: all non-Viewer roles can edit the PWS entry (the Agronomy permission is not factored into edit access).
• Planting and Nitrogen events placed.
• Nitrogen simulation ran. 

Process: 

1. Log into Granular Insights and open the Nitrogen tab. 
2. Click the Projected N icon to view simulation details. 
   • 
3. In the left-hand menu, open Additional Details. 
4. Click Edit Field Details. 
   • 
5. Check Edit Precipitation. 
6. Open the drop-down menu to choose a precipitation event by date. 
   • 
7. Edit precipitation amount in inches. 
   • Note: We can edit events where Granular Nitrogen received precipitation information. To add rainfall when there is no precipitation recorded, add an irrigation event from the field list. 
   • 
8. Click Save to apply changes.
9. A Nitrogen simulation runs automatically. The season chart appears faded and a processing circle covers the field map.  
   • 
10. After N-sim completes, hover over the changed date to view the edited precipitation event. Note that the source is now "pws."
