Improved analysis of solar signals for differential reflectivity monitoring

The Finnish Meteorological Institute (FMI) operates a network of 10 C-band Doppler weather radars, of which nine radars are polarimetric. Every 15 min the radars perform a 30 12-elevation volume scan between 0.3 and 45◦ elevations, where 6 elevations up to 9◦ are scanned in single–PRF with 570 Hz, and then 6 elevations starting from 2 up to 45◦ in dual–PRF.

Every 5 min the first 6 of these 12 elevations are repeated. The dataset contain analyses of so-called 'sunhits' that are detected in the polar volume data produced by the Finnish radars. Datasets are ascii text files where each line represents a datapoint, the content is described in separate 'Readme' files.
