The Arctic Lake Biogeochemistry Model (ALBM) is a one-dimensional process-based lake biogeochemistry model that can simulate the dynamics of water temperature, ice phenology, phytoplankton and four dissolved gases (N2, O2, CO2 and CH4). The model especially focuses on the carbon dynamics of high-latitude lakes, including photosynthesis, autotrophic respiration, aerobic and anaerobic microbial degradation of organic carbon, photochemical degradation of organic carbon, CH4 oxidation, and CH4 ebullition.
Spin-Up Design: A 2-Year spin-up was conducted. During the spin-up period, the ALBM model was driven by the forcing data of 2006 for future runs and the forcing data of 1979 for historical runs.
Potential Evapotranspiration: Please refer to Tan et al. (2015).
Snow Melt: Please refer to Tan et al. (2015).
Additional questions 1
How did you initialise you lake temperature profile?: If the annual mean air temperature of the lake grid is less than 4 deg celsius, the lake temperature profile would be initialized as a uniform 4 deg celsius profile at the start of the spin-up. Otherwise, the lake temperature profile would be initialized as a uniform profile equal to the annual mean value at the start of the spin-up.
How did you set lake depth?: The lake depth is set according to the ISIMIP provided dataset.
How did you set water transparency?: The lake water transparency is set according to the method of Subin et al. (2013) used by the CLM lake model.
