DATA-SPECIFIC INFORMATION FOR: [Alert_solar data set. Weather variables collected at our Alert field site]

1. Number of variables: 20

2. Number of cases/rows: 153,860

3. Variable List: 

Year == The year on which the weather variable  was recorded

Month == The month on which the weather variable was recorded

day == The day on which the weather variable was recorded

hour == The hour at which the weather variable was recorded

minute == 1 minute averages of the weather variables time stamped at the ned of the minute

date == The Year, Month, day, hour, and minute columns combined into one column

SWD == Downwelling broadband shortwave flux [Wm^-2] calculated as the sum of the contributions from the diffuse and direct beam (DIF + DIR)

DIF == Shortwave diffuse flux [Wm^-2]

DIR == Shortwave direct flux [ Wm^-2]

SWU == Upwelling (reflected) shortwave flux [Wm^-2]

LWD == Downwelling longwave flux [Wm^-2]

LWU == Upwelling longwave flux [Wm^-2]

Tair == Air temperature at 3 m height [C]

RH == Relative humidity at 3m height [%]

Air_press == Air pressure at 3 m height above the surface (at ~210 asl) [mb]

WS == Wind speed at 3m height [m/s]

WD == Wind direction at 3m height [degrees]

Albedo == Albedo (SWU/SWD); smoothed with a 6-hr running mean

Cloudiness(DIF/SWD) == Diffuse fraction of shortwave radiation representing “cloudiness”

Net_LW(LWD-LWU) == Net longwave radiation.

4. Missing data codes: Missing data represented as NA
