Mariposa Grove Remote Access Weather Station Replacement with Standard Weather Tower
The purpose of this project is to replace the Remote Access Weather Station (RAWS) in the Mariposa Grove with a permanent 'Rohn-type' weather tower. The existing station is a 'tripod' structure typical of RAWS sites and the State of California Department of Water Resources (DWR) would like to replace it with a standard 10-meter (32.8 feet) tall tower. The existing RAWS has a 20 foot tall mast. The proposed tower would be painted black or fabricated with black anodized metal and be anchored by a concrete footer that would be poured into a hole approximately 2 feet in diameter by 4 feet deep. The new tower would host all the standard weather metrics currently collected by the RAWS (temperature, humidity, solar radiation, fuel moisture and temperature, rainfall, and wind speed and direction) as well as snow depth. The tower site is in a clearing not visible from roads or trails and not near any giant sequoia trees.
