      Dear Windy developers,

      There's an issue with the Romanian radar mosaic as it's presented in Windy, and it persists for multiple months as of now. The reflectivity values are significantly lower than in the original maps available at https://www.meteoromania.ro/radarm/radar.index.php.

      An example from today: 26 dBZ on Windy and 35-40 dBZ in the original image.

      The color scale for the original image starts at 5 dBZ and proceeds in 5 dBZ increments.

      The issue has already led to dangerous precedents like the one below, when an extremely severe hail-bearing supercell had reflectivities of mere 45 dBZ.

        Hi @cb-incus, thank You for letting us know.

        So the color scale at meteoromania.ro starts at 5 dBZ and ends at 75 dBZ? Is that correct? Is there any documentation for the color scale?

          @Filip_K Yes, these dBZ values are correct.

          There's an article about the nowcasting system in Romania where the scale can be found: https://www.todaysoftmag.ro/ampArticle/3631/avertizarile-meteorologice-de-tipul-nowcasting.

            I've deployed fix with value of each color set to the center of the interval (7.5, 12.5, ... ,77.5).
            Thank You again for the info.
