Meteorological station Split – Marjan;

SST station Split

• Qs: mean daily values calculated based on hourly values;

• Ql, QE, QC calculated based on daily averaged values of meteorological and SST values; all parameters except SST were measured hourly, SST at 07 and 14 h.

• Missing wind speed in June replaced by daily average from observations at 07, 14, 21 h. using relationship:

W = 0,836B **(3/2)

W is wind speed in m/s B is value

on the Beaufort-scale

Monthly mean air temperature, precipitation, net heat and water flux (evaporation – precipitation) computed for Split-Marjan station for the period 1961-1990 and for 2003 and 2006. Vertical bars represent standard deviations for particular month.

• Surface fluxes will be calculated for all available meteorological and SST values on daily scale (daily average values);

• STATIONS: Split, Hvar, Komiža, Lastovo, Dubrovnik

• Based on ALADIN values surface fluxes will be calculated. For the SST field stations values, and/or satellite values will be calculated.
