Dry Limt meteo stations

Diurnal courses of key variables from the Dry-Limit meteo station network.
Rows from top to bottom show northern (~19.7°S), north Rio Loa (~21°S), central (~21.5°S) and southern transect (25°S).
Columns from left to right: stations from coast (~19m+ ASL) to Andes slope (~2400m ASL).
Times marked as blue indicate fog, times marked in orange are vsit times at the stations.
Selectable plots are:

• Temperature:
  • T_sLW (yellow) = surface temperature from upwelling long wave radiation (master stations only, thin and thick = as measured and corrected)
  • T_surf (orange)= surface temperature measured with IR-thermometer (thin and thick = as measured and corrected)
  • θ (dark and med. red) = potential temperature = air temperature corrected to a height of 2m
  • T_dew (dark and med. green) = dew point temperature
  • T_sky (blue) = sky temperature from downwelling long wave radiaton
  • T_inst (greyish dotted) = internal instrument and logger temperatures
• Wind:
  • wind speed (top)
  • wind direction (bottom)
• Radiation:
  • top:
    • G_toa (black dashed) = theoretical radiation at top of atmosphere
    • SW_dn (light red) = incoming solar radiation (or downwelling short wave or global radiation, two different sensors at master stations)
    • SW_up (light green) = reflected solar radiation (or upwelling short wave radiation, two different sensors at master stations)
    • LW_dn (blue) = donwelling long wave radiation
    • LW_up (red) = upwelling long wave radiation
    • R_net (black) = net radiation (or radiative flux budget, SW_dn-SW_up+LW_dn-LW_up
    • E(T) (grey) = emitted radiation from sensor
  • bottom:
    • Albedo (black) = SW_up / SW_dn
• Pres-Prec:
  • pressure (top)
  • precipitation (bottom)
    • 10min value (black)
    • cumulative sum over the day (magenta)
• Humidity:
  • top: q = specific humidity = mass mixing ratio
    • q_air at two heights (thick, dark and ligh green) = apparent
    • q_sat at two heights (thin, dark and ligh green) = specific humidity at saturation
  • bottom: leaf wetness
• relHum:
  • top: relative humidity at two heights
  • bottom: leaf wetness
• LCL:
  • Lifting condensation level
• Fluxes (only for master stations N3, C3, S3)
  • R_net (black) = net radiative flux
  • H_Bow (red) = turbulent sensible heat flux from Bowen ratio method
  • L_Bow (green) = turbulent latent heat flux from Bowen ratio method (~evaporation)
  • G_Bow (grey) = soil heat flux
• Langley:
  • left: langley plot (solar radiation flux I versus relative airmass μ)
  • right: I versus time. before (open symbols) and after noon (solid symbols)
• Soil:
  • top: soil temperature
    • T_Surf = surface temperature from IR-thermometer (orange) and LW-radiometer (yellow)
    • T_soil = soil temperature at different levels
  • bottom: soil moisture at different depths
• U_Batt:
  • top: Battery Voltage
  • bottom: Internal Temperatures
