Research
We took Kaniska Mallick to Tonzi and Vaira Ranches. Kaniska has been using our data to test and probe his STIC model, so it was a nice opportunity to show him the real system and all the sensors.
It was a nice chance to make a bunch of summer metadata measurements for populating our Ameriflux BADM page. We measured LAI with the Licor 2200 at the uoward camera sites to recalibrate them, took LAI transects and sample tree width rings. Must say the trees looked good despite drought. Early and late rains must have helped. Soil moisture at depth was 18%, tips of trees were green again with new growth. Last few years they had many dead twigs. Was hot, 102F.
As we processed the LAI data we report it is about 0.77. This compares with Youngryel Ryu's dissertation work, circa, 2010 which was about 0.78. This is a nice indicator that despite the many droughts the blue oak trees have faced, they continue to grow and maintain their canopy.
