Sammendrag

The biogeochemical MAGIC model has been applied to the data from the 1995 and 2019 surveys of 1000 Norwegian lakes. The work is a follow-up of a modelling exercise that was done in 2022, with improved input data and with new deposition estimates generated from NILU’s deposition station network. The results indicated that the new deposition data from NILU gave slightly better simulated results (compared to the observed) than those with the deposition estimates from EMEP used in 2022. For future work we recommend that the calibrations to the 2019 data driven by the deposition data from NILU’s deposition station network are used.
