IOMASA

Integrated Observing and Modeling of the Arctic Sea ice and Atmosphere.

At present, the polar regions are among the regions for which the least information is available about current and predicted states of surface and atmosphere.

 

The objective of IOMASA is to improve our knowledge about the Arctic atmosphere by using satellite information which is continuously available, but currently not exploited. This progress will be achieved through an integrated approach, the outcomes of each of these three points serving to improve the other two:

  1. Remote sensing of atmospheric parameters temperature, humidity and cloud liquid water over sea and land ice.
  2. Improved remote sensing of sea ice with more accurate and higher resolved ice concentrations (percentage of ice covered sea surface).
  3. Improved numerical atmospheric models by assimilating the results of points 1 and 2.  

The NSI leads the program for the development of an empirical emissivity and backscatter model for the ice including the sea ice cover. Temporal analysis of the satellite data will be carried out in collaboration with DMI. In collaboration with IUP, existing field data will be utilized for understanding the regional differences in the temporal evolution of the ice signatures. The NSI will assist DMI in the development of the weather correction sea ice concentration algorithm. As an interactive user interface for the real time data will be used, the IWOCOS (Integrated Weather, Sea Ice and Ocean Service System) software, under the responsibility of DTU where this software is currently in use. The NSI's experience with IWICOS will be of direct benefit to the user interface of IOMASA, which is in fact planned as an extension of the IWICOS software.
