I am a P.h.D student working on effects of Evaporation duct on radio propagation. Pandemic is successfully stopping me from obtaining my own measurements for my thesis, but I would like to compare the model I am working on with some real-world data. What I require is data for Atmospheric Pressure, temperature and relative humidity measured in one location at different altitudes. The University of Wyoming has published such a set of data (Available here):
While their data are perfectly fine, the fast ascend in altitudes where data are measured at is not ideal for me. What I require are the heights between 0 and 200 metres. Perhaps any of you know of a place where such data can be found?
