atmos_WindSpeed2m(atmos_windSpeed_m_s, atmos_windMeasureHeight_m)Arguments
- time_dayOfYear_
<1, 366> (d) the number of the day in the year between 1 (1 January) and 365 or 366 (31 December)
- atmos_temperature_Cel
(Cel) the average air temperature in the time phase
- atmos_temperatureMax_Cel
(Cel) the maximal air temperature in the time phase
- atmos_temperatureMin_Cel
(Cel) the minimal air temperature in the time phase
- atmos_relativeHumidity_1
(0, 1) relative humidity
- atmos_solarRadiat_MJ
(MJ/m2/TS) the solar radiation that actually reaches the earths surface
- land_latitude_Degree
(degree) average latitude
- land_elevation_m
(m) average elevation
- atmos_windSpeed_m_s
(m/s) measured wind speed at z m above ground surface
- atmos_windMeasureHeight_m
(m) height of measurement above ground surface
Value
atmos_netRadiat_MJ (MJ/m2/TS) the balance between the energy absorbed, reflected and emitted by the earths surface or the difference between the incoming net shortwave (Rns) and the net outgoing longwave (Rnl) radiation
atmos_netRadiat_MJ (MJ/m2/TS) the balance between the energy absorbed, reflected and emitted by the earth's surface or the difference between the incoming net shortwave (Rns) and the net outgoing longwave (Rnl) radiation
atmos_vaporPress_hPa (hPa) actual vapour pressure, can be calculated by atmos_VaporPress()
atmos_WindSpeed2m_m_s (m/s) wind speed at 2 m above ground surface
