From May 28 to July 4, 2008, albedo observation was carried out in the desert transition zone in the intensive observation area of Linze station and Linze station. Observation quadrat and target: A9 quadrat edge and ly07 quadrat edge of desert North-South Transect (pure sand, sandy plants, dried annual herbs), Linze station (flax, corn, tomato).
Observation instrument: kippzonen Cmp3 shortwave meter (the number of the above table is 071391 and the number of the following table is 071390), and the measurement spectrum range is 310nm-2800nm. Recording method: from May 28 to June 22, use Shenzhen unit ut58 multimeter to record the upward and downward voltage values manually, convert them into upward and downward irradiance during pretreatment, and calculate the albedo with a recording interval of 2 minutes; From June 25 to July 4, the American Campbell CR1000 data acquisition is used for automatic recording, and the recording interval is 1 second. The self recording observation data file contains the following information: timestamp, 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 = solar_ DOWN_ AVG / SOLAR_ UP_ AVG、batt_ volt_ Min (battery voltage), pTemp (CR1000 panel temperature).
Erection height of shortwave meter: the two meters are about 1m from the ground, and the leveling bubble is leveled. Data storage: the manually recorded data is in Excel form, and the self recorded data is in. Dat file. After processing, the data is saved in Excel form, and the original data includes the photos of observation points. Observation time: May 28, June 5, June 6, June 15, June 22, June 25, June 30 and July 4, 2008.
The experimental observation quadrats are the A9 quadrat edge and ly07 quadrat edge of the North-South desert Transect (pure sand, sandy plants, dried annual herbs) and Linze station (flax, corn, tomato).
Observation instrument: kippzonen Cmp3 short wave meter (the number of the above table is 071391 and the number of the following table is 071390), and the measurement spectrum range is 10nm-2800nm. Recording method: from May 28 to June 22, use Shenzhen unit ut58 multimeter to record the upward and downward voltage values manually, convert them into upward and downward irradiance during pretreatment, and calculate the albedo with a recording interval of 2 minutes; From June 25 to July 4, the American Campbell CR1000 data acquisition is used for automatic recording, and the recording interval is 1 second. The self recording observation data file contains the following information: timestamp, 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 = solar_ DOWN_ AVG / SOLAR_ UP_ AVG、batt_ volt_ Min (battery voltage), pTemp (CR1000 panel temperature). Erection height of shortwave meter: the two meters are about 1m from the ground, and the leveling bubble is leveled.
During the period from May 28 to June 22, the upward and downward voltage values are recorded manually with Shenzhen unit ut58 multimeter, which are converted into upward and downward irradiance during pretreatment. The recording interval is 2 minutes when calculating the albedo; From June 25 to July 4, the American Campbell CR1000 data acquisition is used for automatic recording, and the recording interval is 1 second.
Good data quality
