STATUS: Active, Real-Time
ABOUT THIS DATA:
The hourly air temperature, dew point temperature, relative humidity, station air pressure, Δ24HR air pressure, incoming solar radiation, average wind speed and precipitation measured at the RVCA Westport weather station (RVCA-WPT1). The daily maximum, minimum and mean air temperature, total precipitation, 30-day moving total precipitation and 90-day moving total precipitation calculated for the RVCA Westport weather station (RVCA-WPT1).
EQUIPMENT & SENSOR CONFIGURATION:
1) OTT Pluvio2 Precipitation Gauge with 200 cm2 Collection Area; Outfitted with Alter-Type Wind Shield; Orifice mounted at 1.8 meters above ground.
2) Gill Maximet GMX501 Compact Weather Station; Sensor array mounted at 2 meters above ground (WMO Standard for air temperature & relative humidity). Integrated (ultrasonic) wind speed sensor not configured to WMO reccommendations.
