Abstract

There is a lot of modem literature which shows that the vertical heat flux near the surface can be detected by means of modem remote sensing data such as NDVI and thermal infrared temperature (TIR). A contradiction seems to exist in that convective vertical flux of sensible heat over a pine forest is not proportional to TIR temperatures as measured by satellites and low flying aircraft. Measurement of temperature, humidity, vertical velocity and thus vertical heat flux, TIR temperatures and others are done by means of a powered glider over different types of vegetation. For normal arable land at very low altitude correlations between vertical heat flux and TIR temperatures are found, but not over pine forests. An explanation is given about the possible reasons for such a contradiction.
