Longitudinal variation with latitude (R script)
lat = 0
long_dd_km <- 6378.145 * 2 * atan2(sqrt(cos(lat * pi/180)^2 * 7.615242e-05), sqrt(1 - cos(lat * pi/180)^2 * 7.615242e-05))

INOGO reference library completed
http://inogo.stanford.edu/libraries/biblioteca-de-referencia
More than 400 hours of work over a year by a small team. A new excellent resource for documents of the Osa and Golfito region. Please contact me if you would like access to any of these documents while we work out the online downloading approach (eventually via inogo.stanford.edu).

With the excellent help of Cam and Rikke we brought the two top of canopy climate towers down and calculated the final wind direction azimuths.
Carrying one of our two 15 foot tower poles out of the forest.
Rigging up for the removal of the high elevation tower.
And a final celebratory climb of a 180 ft. giant redwood. What a view of Laupahoehoe!

Excuse the delay in updates, been overwhelmed with field work, job related activities, remote sensing analysis and modeling for our Amazon project. All is moving well, here is the tally for the Hawaii project:
Canopy LiCOR days left: 3-4.
Understory LiCOR days left: 3-6.
Interior Forest Microclimate Sites left: 3-4.
Biodiversity leaf area density transects: 2-3 days.
Almost there! Wonderful, especially with the intense rains we’ve been having these last weeks.
Here are some nice panoramic photos from recent field work:

Finished tree 4 of 20; a few weeks to go.
Received a new PAR sensor (w/ 28 m cable) to replace one that shorted out in the interior forest micro-climate array. This will also be a good opportunity to test the calibration of the other 3 interior forest sensors.
Heading to the field today to take down interior forest sensors, download top of canopy low and high elevation tower data, replace desiccant, and then perform the PAR calibration back here at the house.
