AB  - This dataset contains chlorophyll data of maize leaves measured using a Chlorophyll Analyzer (SPAD) at the Daman Water Control Experimental Field, EC Station, Super Station, and Shiqiao Site in Zhangye City.   1) Measurement purpose  The purpose of measuring chlorophyll data is to obtain the chlorophyll content of crop leaves on the underlying surface of the Heihe River Basin, which can be used as parameters for vegetation radiative transfer models and inversion of other biophysical parameters.   2) Measuring instruments and principles  Measuring instrument: Chlorophyll analyzer (SPAD).   3) Measurement location and content  a. Daman Wheat Moisture Control Experimental Field  Measure the chlorophyll content of wheat leaves under 12 different water treatments on May 17, May 23, May 29, June 3, June 9, June 14, June 24, July 5, and July 12, 2012.   b. EC site  Measurements were taken on May 14, May 21, May 25, May 31, June 7, June 13, June 23, June 28, July 3, July 13, July 18, July 23, August 3, August 12, and August 28, 2012, respectively EC-2、EC-3、EC-5、EC-6、EC-7、EC-8、EC-9、EC-10、EC-11、EC-12、EC-13、EC-14、EC-15、EC-16 There are a total of 14 EC sites for seed production of corn leaf chlorophyll content.   c. Super Station Sample Site  Measure the chlorophyll content of maize leaves in super station plots on May 22, May 28, June 5, June 11, June 18, June 25, July 1, July 8, July 15, July 22, July 31, August 9, August 15, August 22, September 3, and September 11, 2012.   d. Shiqiao plot  Measure the chlorophyll content of maize leaves in Shiqiao plots on May 17, May 22, May 28, June 4, June 11, June 17, June 25, July 1, July 8, July 15, July 22, July 30, August 8, August 16, August 27, and September 9, 2012.   4) Data processing  Record observation data with an observation notebook at the experimental site and organize it into an Excel spreadsheet.
