AU-MHB

Public advisory work ("myndighedsbetjening") for the Danish Ministry of Environment by the Environmental Engineering Section within the Department of Biological and Chemical Engineering at Aarhus University. Orders are separated into directories with names based on the order numbers. See README.md files in individual directories for details. In some cases, there are connections between directories (the weather results are used in multiple analyses), and these are described in the readme files or the R scripts.

In all cases, each order has (or will ultimately have) an associated report or memo available online. These documents are typically written in Danish.

"Releases" are used in GitHub to make it easy to find the exact version of the repository files associated with the publihsed version of the report or memo. See below for information on releases associated with each order. Most recent orders are on the bottom. All releases can be browsed here.
