Four 3-D Csat3 sonic anemometer / eddy covariance systems along with Krypton
hygrometers set up near Kimberly, Idaho during 1999 as part of the RAPID study
(Regional advection perturbations in an irrigated desert).  Collaboraters included
Univ. Idaho, Wageningen Agricultural Univ., the Netherlands, USDA-ARS,
Campbell Scientific, Utah State University.   The study also included two scintillometer
systems.  Alfalfa field was owned by Kevin Stanger, Hansen, Idaho.

ScinTech scintillometer used to determine sensible heat over a large,
integrated area.  The ScinTech is German made and was used
as a part of the RAPID-Idaho study in 1999..  Large apparture
scintillometers (LAS) are manufactured in Wageningen, the Netherlands
by  MicroMet Scientific under the supervision of the
 Dept. Meteorology of WAU (Dr. Henk deBruin).


Kipp and Zonen four component net radiation system.  The glassed domed
instrument is a short wave pyranometer with both upward and downward
looking sensors.  The open black topped sensor is a full-spectrum radiometer
with upward and downward looling sensors.  This unit was used as a part of the
RAPID-Idaho study in 1999.

Some  preliminary results  and short description of the Idaho RAPID study are
available in pdf format.

2007:  “THE” Dr. Henk de Bruin, Professor of Meteorology at Wageningen University, The Netherlands, alongside a Kipp&Zonen large aperture scintillometer, in New Mexico.  (Henk was instrumental in the LAS development) (note his old orange coat hanging nearby)

Henk de Bruin and Jan Kleissl (UCSD), 2007, tending a LAS on a bluff above the Rio Grande, New Mexico, over salt cedar / cottonwood mix

Henk de Bruin, Jan Hendrickx (New Mexico Tech), Jan Kleissel (UCSD) and Sung-ho Hong (NMT) near an eddy covariance station along the MRG in 2007.  Note that even the ‘experts’ can let the grass get ‘unrepresentative’ (too tall and senescing) beneath the radiometers!!!  Also note that even the ‘experts’ stand nearly underneath and trample the grass nearly underneath the net radiometer system (here a K&Z) !!!  (too busy talking about eddies).
