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
ITHACA period
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.
ITHACA period vs 2003 and climatological mean
• 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.
• AdHOCAdriatic sea Heat and water fluxes – Observation and Calculation.
