    Is the cloud base layer in AGL or MSL?

      Hey there!

      I tried to find this in other posts but couldn't find an answer to my question: on the cloud base layer, are the altitudes given in MSL or AGL? (MSL = mean sea level / AGL = above ground level)

      So basically, 1000ft clouds, does this mean 1000ft above sea level or 1000ft above the ground?

      Thanks a lot!

        Also if you make a search for "cloud base"
        you'll find a lot of usefull info.

          Hi @fst , it is above ground level.

          You can check our list of weather overlays where it is described as follows: "Cloud base height is the altitude of the lowest cloud base above the ground, especially important for pilots. The model of terrain is simplified, so be cautious to use these values in the mountains. On large areas, the forecast model is not able to calculate the cloud base."

          Also the "clock" icon on Windy.com says:

          _center_shadow

          Hope this was helpful.

          Best wishes

            @marienka great, thanks for this info! I was looking in the UI on where to find info about a layer displayed currently but didn't think about that the clock icon could have a tooltip. Now I know :)

              the clock icon is OK for reference time of the model and for update interval,
              but for info. (description) of wx. overlays,
              I think the info. icon is more suitable 0_1541486506959_de9bbe7f-143e-47af-8164-b53ac561e050-εικόνα.png

                  I like the i for "info about the data" (even the reference time would be fine under such icon) but cannot program anything :) , maybe @ivo can take it into consideration?

                  Best wishes

                    When talking about 'cloud bases', the clock icon indicates that the model of terrain is simplified. Can you indicate how that simplification works. I live in the mountains. Does it average valleys and tops of mountains? AGL doesn't mean much unless you know the height of the terrain.

                    An 'i' or a "?" would be better than a clock.

                    Great work by the way.
