HPWREN large met data set

A request from an outside researcher looking for access to 1 Hz wind data from HPWREN meteorological sensors led to the creation of a large downloadable data set across many years. For about two decades HPWREN had already made its sensor data from cameras and met stations publicly available, but the met data was not easily accessible in bulk on HPWREN web pages. That data, as collected from HPWREN's Vaisala WXT5xx weather transmitters, includes second-by-second wind speed and direction, 10 second temperature, relative humidity and atmospheric pressure, as well as up to 10 second rain and hail information, and in some cases extends back to 2008.

HPWREN camera web site improvements

Users will find that the camera banner page is more responsive to screen changes such as resizing or rotation, adding more support for various device types, sizes and display capabilities. The "details" pointers refer to more information about the camera or camera collage at specific sites. The cameras are now sorted alphabetically, and different sort order options will be added over time.

San Diego River Park Foundation Boulder Creek Preserve Environmental Monitoring Research Program

By Robert Mazalewski and Martin Offenhauer

Senior Technical Advisors at the San Diego River Park Foundation

The San Diego River Park Foundation (SDRPF) was created in 2001 to educate the public on the value of the San Diego River watershed and its relationship to our environment. The Upper San Diego River Gorge and the areas that drain into it is, in many places, truly pristine wilderness that are largely within or next to the Cleveland National Forest. The River is a corridor for the movement of many wildlife species and has been considered by some experts as the most biologically diverse area in the entire country.
