approximate grass or soil temp?

can any one please point me in the direction of an approximation to calculate soil or grass temp if you know the other basic variables.

I know there are so many factors influencing temp from 1.25/2m down to zero cm but are there any equations to help?

You can use WXSim to give you that.
In WXSimate, click on the “Soil” button in the bottom right hand corner and add any soil temp & moisture sensors that you have so that the data is picked up during the download.
In WXSim; First go into Start > Autorun and disable the autorun if you use it.
Now on the main page click on the “Soil Data” button to open a new window where you can tell WXSim the type of soil that you have and various other information. Lastly, put a tick in the “Allow soil calculations” box and click OK to close.
Now restart the autorun again.

thanks Budgie - unfortunately I don’t have any extra sensors to help with this - that’s why i wanted to get an approximated value.

Why not try the soil forecast routine in WXSim anyway. It should produce something as I only have one set of temp & moisture sensors and the forecast produces data for more than that. :wink:
