frictional velocity Explanation: Mentioned alongside temperature and cloud cover. -------------------------------------------------- Note added at 1 hr (2015-04-05 23:15:50 GMT) -------------------------------------------------- This data set contains climatological monthly means of heat fluxes and radiation budget over the global oceans, based on analyses of the Comprehensive Ocean-Atmosphere Data Set (COADS) for the period 1950 - 1979. All data are given on a 2 x 2 latitude/longitude grid. Meteorological and oceanographic parameters contained in this data set include air temperature, mixed layer temperature, precipitation, relative humidity, cloud cover, wind speed, sea level pressure, salinity, absorbed solar radiation, outgoing longwave radiation, net radiation, latent heat flux, sensible heat flux, net downward heat flux, net freshwater flux, buoyancy flux, frictional velocity, newtonian cooling rate, and transfer coefficient for latent heat. Precipitation data were prepared by Dennis Shea. It was derived from land or island station records and completed by satellite observations. Salinity data required to compute buoyancy fluxes were taken from Levitus. All input data were monthly mean climatological values except the surface salinity. Because of the small variation of the climatological mean surface salinity throughout the year, annual mean values were used. http://iridl.ldeo.columbia.edu/SOURCES/.OBERHUBER/.dataset_d... cccccccccccccccccccccccccccccccccc Estimation of regional evaporation under different weather conditions from satellite and meteorological data: a case study in the Naivasha basin, Kenya (2001) Existing remote sensing algorithms used to estimate evaporation from remotely sensed data differ in the way they describe the spatial variations of input parameters.

friction velocity Explanation: Dane meteorologiczne: Podstawowe dane meteorologiczne to wysokość warstwy granicznej (mieszania), długość Monina-Obuchowa, prędkość i kierunek wiatru, prędkość tarciowa, wielkość opadów, zachmurzenie, strumieńciepła przy powierzchni ziemi, częstość prądów konwekcyjnych ponad warstwą mieszania. Niektórez tych wielkości są dostępne jako dane pomiarowe, inne są obliczane przy użyciu odpowiednichalgorytmów. - - http://goo.gl/AQVDHh - page 31 ----------- Output includes hourly values for mixing heights and Monin-Obukhov lengths, surface friction velocity, convective velocity scale, and profiles of wind speed and direction, temperature and turbulence - - http://www.epa.gov/scram001/7thconf/aermod/compar.pdf - page 11 -------------------------------------------------- Note added at 1 hr (2015-04-05 23:21:21 GMT) -------------------------------------------------- Friction velocity Friction velocity is a very important term in some models of air-sea interaction. It can also be estimated through remote sensing of water surfaces: NSCAT observations can be used to calculate friction velocity as an alternative to wind speed. Since friction velocity is the square-root of the kinematic stress, these observations can easily be used to estimate the stress. Close to the surface, friction velocity is not a function of height. Furthermore, for modeling purposes, it is the near surface value that is of interest. An observed friction velocity is a great advantage over wind (and equivalent neutral wind) because the dependence on atmospheric stability is (in theory) contained in the observation, and does not require an adjustment dependent on atmospheric stability (Bourassa et al. 1999). http://coaps.fsu.edu/~bourassa/scat_html/forcing_tut/forcing... |
