SMAPVEX19-22 Massachusetts Plant Area Index, Version 1

These data consist of plant area index (PAI) and the RGB images from which the PAI values were derived. Data image files were taken between April 2019 to December 2022 in the vicinity of Petersham, Massachusetts during the SMAPVEX19-22 (Soil Moisture Active Passive Validation Experiment 2019-2022) field campaign. The location was chosen due to its forested land cover, as SMAPVEX19-22 aims to validate satellite derived soil moisture estimates in forested areas.
