Climatologic monthly data AVHRR NOAA (calibrated albedo and surface temperature, NDVI) are used to inquire
into a question on correlation between albedo and surface temperature in Sonara desert. Our study demonstrate negative
correlation between these parameters (radiation thermo-regulation) during dry period from April to beginning
of July. Correlation became positive over the North American monsoons peak period (second half of July - beginning
of September), evapotranspiration thermo-regulation begin to prevail. Correlation is indistinct during the rest of
the year. NDVI critical value (radiation thermo-regulation prevail below this level) is determined.
Keywords: albedo, surface temperature, NDVI, correlation, feedbacks, green phytomass, Sonora desert, Northwest Mexico
