Do you provide real measurement data, and what are the limitations or reliability issues of such data?

Availability of measurement data:
The measurement data come mainly from weather stations, weather balloons ("soundings"), or - if available - from buoys (on the water). meteoblue has access to a large number of different weather stations operated by third-party data providers.
Limitations of measurement data:
Measurements from weather stations are the most exact weather data we can obtain for a location, but they have some limitations:- Measurements are available only for less than 1% of the Earth's surface;
- Sensors can break and then not deliver any data
- Wrongly installed measurement devices may cause wrong or even no measurements
- Extraordinary events (e.g. wind turbulences, irrigation) causing wrongly measured values
- Reflections can falsify the radiation measurement
- Dirty sensors cannot observe the total amount of precipitation or radiation
- Transmission problems leading to interruptions or distortion of data supply.
As a consequence, we cannot guarantee measurement data availability and quality. We can, however, optionally offer to improve the output of the measurements:
- Gap-filling, using ERA5 reanalysis model data, which is also using measurements /observations reaching a high accuracy
- Quality control, automatically filtering out implausible, negative values
- Special reports and analyses of possible deviations.

An overview of the available weather stations and their global distribution is attached to this email.
Hi Miloslav,
The quote mentions an attachment which is not (yet) available here on forum. Do you plan to include it?
Thanks! -

Yes, working on it :)
