GGCMI Phase 2 masks and growing season input data (Q6689)

Growing season data for crops as supplied to modelers in the GGCMI Phase 2 experiment (Franke et al. 2020). Other than for wheat, which is split in spring wheat and winter wheat in Phase 2, the growing season input data is the same as in Phase 1 (Elliott et al. 2015). A boolean mask on what regions can be excluded from the simulations, modeling all crops and irrigation systems everywhere otherwise. A mask assigning harvested wheat areas to winter or spring wheat.
