Global heterotrophic respiration estimates derived from carbon balance

This repository contains global, gridded monthly heterotrophic respiration estimates across the period 2010-2012 obtained by inverting the land surface carbon balance. Net ecosystem productivity is obtained from CMS-Flux (Bowman et al, 2017 see http://cmsflux.jpl.nasa.gov/), gross primary productivity is obtained from scaled solar-induced fluorescence estimates from GOME-2 (Parazoo et al, 2014), and autotrophic respiration is estimated based on gross primary productivity and a spatially variable, temporally constant vegetation carbon use efficiency obtained from the C Data Model Framework - CARDAMOM (Bloom et al, 2016). The inversion provides uncertainty estimates constrained on all gross fluxes having physically meaningful signs. Sample code for the inversion is included.
