Description

As reported by Henk, there is a bug in the nudging of HNO3 in the stratosphere based on ODIN data.

The data are given as the ratio of the volume mixing ratios of HNO3 over O3. To calculate the corresponding target HNO3 mass in a grid box, the observed volume ratio should be multiplied by the O3 mass and the ratio of the molar mass of HNO3 over that of O3, which is about 1.31. The latter factor is currently missing.
