More research and development of MM5 thanks to Lorenzo Claveri

Work within EU-project (3 years in Helsinki)

Main objectives to start with are:

- How to handle surface temperature (SST/Skin temp.)

- Sea ice; correctness of data input and effect on MM5

- First test case; Pori and also surrounding coastal area, investigating stable condition and low-level jet
