Thinned posterior distributions from Swiss Breeding Bird Atlas abundance models

Data & Format

Species Abundance Files: All 71 species-specific .zip files posterior distributions of abundance from Swiss Breeding Bird Atlas abundance models (Knaus et al. 2018). For each species, there are posterior distributions for the 1993-1996 and the 2013-2016 atlas periods. These are thinned versions of the full posterior distributions (1500 samples) and have been masked to eliminate areas outside of the borders of Switzerland and Liechtenstein. Very low abundances (< 0.1) were set to 0 and unrealistically high abundances (> 0.99th quantile of predicted abundances, were set to the 99th quantile). All methods were in line with the best practices and published atlas products by the Swiss Ornihtological Institute. All .txt files contain coordinates of square kms throughout Switzerland, mean elevations within square kms, and 1500 samples of predicted abundance (all samples start with V). Files are named by species in german.
