Brutsaert (in his book "Evaporation into the atmosphere: theory, history and applications") showed that the value of kB-1 can range from 2 for total cover crops to a wet soil at 8.5 for a dry and dry ground with a moderate wind speeds. For this purpose, it is possible to exploit the trapezoid relationship between NDVI and land surface temperature (obtained with remote sensing data) in a perspective of approximate estimate of kB-1 and consequently the roughness length for heat transport (z0h)?
Hi,
Yes, this is very possible especially when you use SEBAL model. You could read the SEBAL manual for further instructions.
Thanks, but in SEBAL, authors use kB-1 equal to 2.3 (i.e zoh= 0.1. zom) that is not very robust approach.
Ok, please could you provide the page number of the particular page you referred to?
Thanks!
Hi,
Thanks for the manual, however, that seems very old. Have you tried to go through the newer version?
Cheers!
Thank you for the new manual. i will read it and if l will have any question i ask you.
My very best regards
