Atmospheric remote sensing

SMHI conducts research in the field of atmospheric remote sensing. The main focus of the research group is on cloud and precipitation retrievals using satellite and radar measurements. The research is directed towards operational meteorology, hydrology and oceanography and also climate applications. 

A majority of the research is done as part of international projects where co-operation takes place with several other European countries.

Satellite data provide insight into melting Arctic ice

In September 2012, the smallest ice spread to date in the Arctic was recorded. With data from satellites, scientists at SMHI have analysed changes in the atmosphere, and then compared the conditions for the ice melt in 2012 with 2007, the previous record low for ice spread.

Satellite observations are essential in climate research

In climate research cloudiness is an important parameter to study, in order to understand what is happening with the radiation balance of the planet and its atmosphere. The SMHI research participates in a project which involves development of statistics on cloudiness conditions, which among other things can be used in evaluation and improvement of climate models.

There is a demand for automatic cloud analysis in a number of areas

The information from weather satellites is an important part of both research and operational meteorology. The SMHI research involves development and improvement of algorithms and software for automated satellite image information. The atmospheric remote sensing research is a part of a European project called Nowcasting SAF.

Interesting remote sensing images

This RGB from NOAA19, 25th of June 12.22utc, show the low pressure which move up over Sweden. The low pressure give heavy rain and Målilla measured 51 mm. During lunch time, SMHI head office in Norrköping, is in the eye of the low pressure. For some minutes we saw the sun. But then the rain started again. The radar composit is from 12.15 utc.
