Map of growing stock volume of Russian forests for the year 2014

The data products consist of two layers that include estimates of<br> 1. growing stock volume (GSV, unit: m3/ha) for the year 2014 (raster data set)<br> Definition: volume of all living trees more than 6 cm in diameter at breast height measured over bark from ground to a top stem diameter of 0 cm. Excludes: branches, twigs, foliage, flowers, seeds, stump and roots.<br> 2. per-pixel of growing stock volume uncertainty expressed as standard error in m3/ha (raster data set) The maps have a spatial resolution of 3.2 arc sec (ca 0.5 ha for Russia). The GSV estimates were obtained by calibration of two remote sensing-based maps with ca 8000 ground plots from the National Forest Inventory:<br> • The global GlobBiomass map of GSV (Santoro, 2018; Santoro et al., 2020) is based on synthetic aperture radar (SAR) observations acquired around the year 2010 and has a spatial resolution of 100m, units m³ ha^-1.<br> • The global Climate Change Initiative (CCI) Biomass map of AGB (Santoro and Cartus, 2019) is also based on SAR data, acquired in 2017 and has a spatial resolution of 100m, units t ha^-1.
