Synchronous observation data set of soil surface roughness in the upstream of Luan River (2018)

The soil surface roughness data set measured simultaneously during the Soil Moisture Experiment in the Luan River (SMELR) in 2018, which covers (1) 30 quadrats in the north-south flight region of 70 km ×12 km typical experimental area, and (2) 8 quadrats in the northeast-southwest flight region of 165 km×5 km complex experimental area. The data were measured on September 17, September 18 and September 20, 2018 respectively. The soil surface roughness along the row (East-West) direction and cross the row (North-South) direction of typical features in each sample area were measured. The surface roughness of the dataset is described using three parameters; root mean square height (RMSH) and correlation length (CL). The root mean square height describes the random surface characteristics, while the correlation length and correlation function describe the periodicity of the surface. The surface roughness was calculated through the steps of soil surface height digitization, slope correction, periodic correction, and roughness calculation.

File naming and required software

The surface roughness data file is LuanRiver_Surface_Roughness.xls. This file contains two sheets with name of corresponding flight region. There are two roughness parameters including RMSH and CL at two directions for each quarter, for which 01 indicates along row(east-west) direction and 02 indicates cross row (south-north) direction.
The location and land cover of sampling site file is Sampling_Location.xls, which contains name of the quadrat, the land cover and the longitude and latitude of the sampling location.
