观测内容包括：

\n

\n

1）2008年12月5日、12月6日、12月7日在冰沟寒区水文气象观测站附近选择积雪场进行积雪光谱的随机观测。\n

\n

2）2008年12月10日在BG-A研究区进行MODIS和Terra MISR同步积雪光谱观测。\n

\n

3）2008年12月13日、12月14日在BG-A进行的积雪纯像元和混合像元光谱特征分析试验。\n

\n

4）2008年12月15日在BG-A选择积雪场进行积雪多角度光谱特征观测，使用的是寒旱所自制多角度观测架。\n

During the pre-test, snow spectral observation was carried out in the intensive observation area of Binggou basin from December 5 to December 15, 2007. There are two purposes of observation: one is to test the feasibility of the predetermined observation scheme; The second is to provide validation data set for remote sensing inversion. All data were obtained by ASD spectrometer (spectrometer of Xinjiang Meteorological Bureau)

\n

Observation contents include:

\n

1) The snow field was selected near the hydrometeorological observation station in Binggou cold area on December 5, December 6 and December 7, 2008 for random observation of snow spectrum.\n

\n

2) On December 10, 2008, MODIS and Terra MISR synchronous snow spectrum observation was carried out in bg-a study area.\n

\n

3) The spectral characteristic analysis test of snow pure pixel and mixed pixel was carried out in bg-a on December 13 and December 14, 2008.\n

\n

4) On December 15, 2008, the snow field was selected at bg-a to observe the multi angle spectral characteristics of snow, using the multi angle observation frame made by the Institute of cold and drought.\n

\n

The data set includes seven subfolders, named according to the measurement date. The measurement dates are December 5, December 6, December 7, December 10, December 13, December 14 and December 15, 2007 respectively. Each folder contains original data and preprocessed data, with data description.\n
