WATER: Dateset of GPR (Ground Penetration Radar) observations in the A'rou foci experimental area from Mar to Jun , 2008

The dateset of GPR (Ground Penetration Radar) observations was obtained in the A'rou foci experimental area from Mar. 10 to Jun. 19, 2008. Those provide reliable dataset for retrieval of soil moisture and frozen depth from GPR observations. Observation items, sites and time were as follows: (1) GPR in No. 1 quadrate of A'rou on Mar. 10, 2008 (2) GPR+TDR in No. 2 and 3 quadrates of A'rou on Mar. 11, 2008 (3) GPR in No. 1 quadrate of A'rou on Mar. 12, 2008 (4) GPR in No. 2 quadrate of A'rou on Mar. 14, 2008 (5) GPR +TDR in No. 1 quadrate of A'rou on Mar. 15, 2008 (6) GPR +TDR in L6 of A'rou on Mar. 16, 2008 (7) GPR +TDR in L6 of A'rou on Mar. 17, 2008 (8) GPR +TDR in L6 of A'rou on Mar. 18, 2008 (9) GPR +TDR in L6 of A'rou on Mar. 19, 2008 (10) GPR in L6 of A'rou on Mar. 20, 2008 (11) GPR +TDR in No. 3 quadrate of A'rou on Mar. 21, 2008 (12) GPR in No. 1 and 3 quadrates of A'rou on May. 31, 2008 (13) GPR in No. 1 quadrate of A'rou on Jun. 20, 2008

WATER: Dataset of ground truth measurement synchronizing with the airborne microwave radiometers (L&K bands) mission in the Biandukou foci experimental area on May 25, 2008

The dataset of ground truth measurement synchronizing with the airborne microwave radiometers (L&K bands) mission was obtained in the Biandukou foci experimental area on May 25, 2008. Observation items included: (1) the soil temperature in L1, L2, L3, L4, L5, L6 and L7; (2) roughness measured by the roughness grid board and collected by the digital camera. Files with "result" field were processed data, in which the first row was RMS height (cm; one value), the second row was distance (cm), and the third row was correlation function (cm; changed into correlation length when it is 1/e). (3) GPR and TDR data. Five files were included, roughness photos and preprocessed data, the soil temperature, coordinates of quadrates and sampling lines, GPR and microwave radiometer data. All were archived as Excel and .txt files. Those provide reliable ground data for development and validation of soil moisture and freeze/thaw algorithms from active remote sensing approaches.
