Hello Heiko, thanks for the requests. Re x|y_wind_gust, for consistency with existing names would x_wind_speed_of_gust and y_wind_speed_of_gust be OK, for consistency with the existing name wind_speed_of_gust?
The description of graupel should be included in this definition. For example "Graupel is precipitation that forms when supercooled droplets of water are collected and freeze on a falling snowflake, forming a 2–5 mm (0.079–0.197 in) ball of rime." Stolen from wikipedia, you may have better/preferred language. Re the name graupelfall_amount, my web search found only uses that treat graupel as a separate word (except in German), so is graupel_fall_amount acceptable? I know it doesn't match the existing snowfall/rainfall etc., but those are common English words. For inland_water_area_fraction, I don't know how to interpret 'inland water ... is all water-surfaces which are not "sea" '. Are bays, fjords, etc. inland water? Is there a clear transition at the river delta of which part is inland and which is not? For CF this may not be essential, but if the answers are well known it would be helpful to state them. (And if not, maybe just say something like 'inland water does not include any ocean or sea'.)
