Rocking L Ranch

Rocking L Ranch is located in the Sierra Nevada foothills 20 miles south of Yosemite National Park. We are a private ranch not open to the public. Rocking L started transmitting weather data in November of 2010 with data upload to Weather Underground as KCANORTH19 and Rocking L Ranch, PWS Weather as KCANORTH19, FindU and CWOP as NV6B, Ham Weather APRS as NV6B, Southwestern Weather Network and MesoWest as AT957. In addition NOAA uses our data for local weather conditions. Being located in the Sierra Nevada foothills leads to microclimate conditions, causing small variances from weather station to weather station. This is normal and all uploaded data is accurate and constantly checked for accuracy by and MesoWest. Our weather station consists of a Davis wireless Vantage Pro 2 and is air aspirated to help keep temperature and humidity readings more accurate. A heater is included in the rain collection unit to eliminate freezing conditions; the heater is thermostatically controlled to eliminate temperature errors. The anemometer is located on a tower in the clear and has its own wireless transmitter back to the console. Data is collected by an ACER server running Windows 7 Ultimate 64 bit with VWS software for ftp uploading and Storm Predator radar imaging software. Data is sent rapid fire to Weather Underground and updated every 5 minutes to the other sites.  Webcam images are provided by a StarDot SC 1.3 mega pixel camera housed in an all weather security housing and is pointed north towards Goat Mountain.  Images are uploaded every 7 seconds and are available on Weather Underground and our Link.  Annual average total rainfall as measured from October 1st through September 30th is 40”. Annual average total snowfall is 24” making for a wonderful winter scene. We are located above the San Joaquin Valley fog and below deep snow which would make travel difficult.
