Dear All,

I am using type 703 and I have a question regarding parameters 8,9,10 which refer to the surface temperature- temperature of undisturbed soil. What does 'undisturbed soil' mean exactly? I can get measurements from local weather stations regarding the soil temperature at various depths; hourly values measured at 10cm depth, daily values taken at 9am for 30cm and 100cm depth.

If I use average soil temperature measurements for 10cm depth, would that be a correct dataset to use in orfed to derive mean surface temperature, amplitude of surface temperature and day of min surface temperature? Would surface temperature differ a lot from the soil temperature at 10cm? Thank you in advance

Best Regards

Eleni
