A bad PWS in Chisinau, Moldova - what can be done?
Hello,
I've noticed that the madis-F4072 PWS, located in Chisinau, Moldova, often reports temperatures that are too high. The problem appears during daytime hours only and is most severe in sunny weather, when the temperatures can be up to 3-7 degrees Celsius higher compared to other PWSes in the city and official stations. This hints to inadequate sun shielding as being the root cause of the overestimated temperatures.
This station uploads data to Weather Underground as well, under the ID ICHIINU9 (I've compared the readings at the same time moments - they are identical). Using the WU archive, I've made a plot of daily maximum temperatures at different stations in Chisinau during July 2024, when anomalously hot and sunny weather was prevalent. The overestimation is clearly seen.
I wonder if it is possible to contact the owner of the station in order to fix the shielding or stop reporting temperature (and likely dewpoint) data, for example?
I can provide more comparisons if it's required.

RE: Too low reflectivity values for the Romanian radar mosaic
@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.

Too low reflectivity values for the Romanian radar mosaic
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.
