2.4. Requested Form of Acknowledgement.
The following reference should be added in the reference list. In addition, when
the use of the data are extensive, it should also be mentioned in the acknowledgement
section that the data sets were collected under the RAISE (the Rangelands
Atmosphere-Hydrosphere-Biosphere Interaction Study Experiment in Northeastern
Asia) project funded by the Core Research for Evolutional Science and Technology
(CREST) program of the Japan Science and Technology Agency.

3. EQUIPMENT
3.1. Instrument Description.
3.1.1. Platform (Satellite, Aircraft, Ground, Person...).
Ground
3.1.2. Mission Objectives.
Measurement of regional sensible heat flux.
3.1.3. Key Variables.
Structure parameter of refractive index.
3.1.4. Instrument Measurement Geometry.
scintillometer placed on the ground. The spatial location was variable.
3.2. Calibration.
no calibration was made.
4. PROCEDURE
5.1. Data Acquisition Methods.
The transmitter of scintillometer was placed at the fixed point, adjacent to the eddy
covariance system near KBU (A1). The placement of the receiver was changed on daily
basis.
6.2. Spatial Characteristics (+).
This is a data set based on point measurement
6.2.1. Spatial Coverage (+).
Vicinity of the KBU village.
Detailed information on the location and the height of the tranceiver and the
receiver, and their distance is given below.
