Output: Seasonal temperature map

The color map to the left shows a typical annual temperature cycle in time-depth coordinates. A left-click somewhere in the plot will call the script calculating the vertical temperature profile on the corresponding day of the year.

Model Input: Lake parameters
I. Enter lake coordinates:Lat (-90..90):Lon (-180..180):
or choose location by a singe left-click on the map
II. Provide the mean depth of the lake: metres
III. Choose the water type:

To run the model with another input:

Enter lake parameters in the panel to the left:
  1. latitude and longitude of the lake (full degrees)
  2. mean lake depth (not the maximum one!)
  3. an estimation of the water transparency
Press (Re)calculate to start the model
Typical calculation time is 10-30s (it takes longer for deeper lakes)
