And as a special, we have used their 300m meteorological tower. For remote temperature profiling we have used microwave temperature profiler MTP-5HE (“ATTEX”, Russia). The remote sensing instrument has been installed at about 700m East from the meteorological tower. The information about rain precipitation along the path between remote sensing instrument site and the tower were provided by 3 micro-radar rain sensors DROP (“Aqua Nubis”, Russia ).

Conclusions On figure are shown the example of time series with the rain (intensity less than 0.12 mm/min or 7.2 mm/h during about one hour) when there is no influences in comparison of the tower and profiler data. It mean that the rain condition isn’t enough to destroy the microwave remote measurement, but of course, it should to get some limitation on accuracy of remote sensing. By any way, the effect of the rain condition can not be longer than the period of the rain.
