Please I am estimating ET from Landsat 7 imagery. I followed the SEBAL manual by Prof Allen and it has really been helpful. I have run through the model in Erdas Imagine and the metric spreadsheet and have obtained all the coefficient of a and b. However, I am stucked on the next step on how to obtain the corrected Sensible Heat Flux H. Though the manual stated the parameters to input which I have already obtained, (Step 3 of appendix 8) I don't know the relation between them. Please can anyone direct me on this. I will be glad if anyone can give me the model or the relation for computing the corrected Sensible Heat Flux (H) . Thank you. See attached SEBAL manual by Allen, 2002
