For evaluating the LAI (Leaf Area Index) data quality, the data validation should be necessary. The ground station observation data plays critical role for the IAI data validation. For doing so, two steps for the data pre-processing should be taken in the LAI data validation progress. One is the spatial representativeness evaluation and the other one is the spatiotemporal upscaling. Based on the 28 ground station data from FLUXET and the Chinese Ecosystem Research Network (CERN) in Asia and North American, the GUGM (Grading and Upscaling of Ground Measurements) model was applied in the data pre-processing. The LAI Validation Dataset based on 28 Ground Stations in Asia and North American (1km Grid, 2001-2011) is consisted of 924 validation records in 28 stations in Asian and North American. In which, 508 records from 16 stations are for forest (55.0%), 341 Records from 11 stations for agriculture (36.9%), 75 records from one station for grassland (8.1%). The dataset is archived in .xlsx and .kmz data format with the data size of 92.4 KB.
