From May 25 to July 11, 2008, two upward and downward short wave radiation meters (above table No.: 071392) were used at the temporary sample points of sample a (reed land), sample B (saline alkali land), sample C (saline alkali land), sample D (alfalfa land), sample e (barley land) and cement land in the intensive observation area of Linze grassland The following table (No.: 071389) continuously measured the upward and downward irradiance of different underlying surfaces to calculate the surface albedo. The data set provides validation data for albedo inversion of airborne spaceborne remote sensing data. On or before June 6, 2008, it was observed manually, and the probe erection height ranged from 1.3m to 1.46M; After that, it is automatic observation, and the probe erection height is 1.20m or 1.30M.
The time, place and surface type of each observation are as follows:
Sample e (barley field) on May 25, 2008
Sample D (alfalfa field) on May 26, 2008
Sample D (alfalfa field) on May 27, 2008
Sample e (cumin bare land) on May 28, 2008
Sample e (cumin bare land) on May 30, 2008
Sample a (reed land) on June 1, 2008
Sample B (saline alkali land) on June 2, 2008
Sample a (reed land) on June 3, 2008
Temporary sample points of cement land in the hospital on June 4, 2008
Cumin bare land near sample E on June 6, 2008
Sample a (reed land) on June 20, 2008
Sample a (reed land) on June 22, 2008
Sample D (alfalfa field) on June 23, 2008
Sample e (barley field) on June 24, 2008
Sample e (barley field) on July 11, 2008
The self recording observation data file contains the following information:
Timestamp: observation time
SOLAR_ UP_ AVG: downlink short wave radiation (measured by upward radiometer)
SOLAR_ DOWN_ AVG: uplink short wave radiation (measured by downward radiometer)
SOLAR_ NET_ AVG: net radiation = solar_ UP_ AVG - SOLAR_ DOWN_ AVG
albedo_ AVG: albedo = solar_ DOWN_ AVG / SOLAR_ UP_ AVG
batt_ volt_ Min: battery voltage
PTemp: CR1000 panel temperature.
This data set includes albedo folders measured in different areas on different dates. Each folder includes photo folders of measurement points and excel tables of measured albedo data; Header description TXT document and data quality description TXT document. See metadata "Heihe integrated remote sensing joint experiment: layout of quadrat transects in Linze grassland densified observation area" for the distribution information of quadrat transects
