Short summary

The satellite-based fractional cloud cover and cloud top height from CLARA-A2 data record has been used to analyse trends in the Baltic Sea region, 1982–2015. Cloud observations from the Tartu-Tõravere meteorological station were used as reference data for the same period. A downward trend in fractional cloud cover in March over the 1982–2015 period was found. For cloud top heights summer and spring regional averages showed opposite signs of the trend: for June positive and for March negative.
