Current weather at Cabauw

Description of the nine panels going from top left via top right downward. Date is given in the title as <yyyymmdd>. On the x-axis time is given in UTC. Adding 20 minutes to UTC gives local mean solar time.

Radiation

Short wave (solar) incoming (SWD) and outgoing (SWU) radiation. Long wave (thermal) incoming (LWD) and outgoing (LWU) radiation. Also displayed is model data for clear-sky radiation (GLOBCL).

Precipitation

Rain amounts (RAIN) in mm per 10 minutes, rain duration (RDUR) in fraction of time and accumulated rain amount (SUM/10) over the last 24 hours.

Pressure

Surface pressure (P0)

Wind speed

Wind speeds at six levels along the tower, at 200 m (F200), ..., at 10 m (F010).

Wind direction

Wind direction at six levels along the tower, at 200 m (D200), ..., at 10 m (D010).

Visibility

Visibility observed at 2 m height (ZMA). Scale is logarithic in powers of 10. 3 -> 10^3 m = 1000 m = 1 km

Potential temperature

Potential temperature at seven levels along the tower, at 200 m (TP200), ..., at 2 m (TP002). Air temperatures are corrected for the neutral lapse rate. When the boundary layer is well mixed potential temperatures should be the same at different levels.

Dew point temperature

Dew point temperature at seven levels along the tower, at 200 m (TD200), ..., at 2 m (TD002), a measure for the humidity content of the air

Dew point depression

Dew point depression at seven levels along the tower, at 200 m (DPR200), ..., at 2 m (DPR002), defined as the difference between air temperature and dew point temperature. A measure for how close the air is to saturation
