PBL is one key physical quantities aimed at analysing the condition of air pollution in an area of interest.
From WRF simulation, I can get the variable
PBLH whixh represents the PBL height.
But, is there any free data source offering the
observing PBL height all over the World?
For now, I can get the weather data from the NOAA weather center. The data based on observations at airports doesn't conclude the quantitative information of PBL.
Any recommendation would be appreciate!
