Model outputs for publication 'Thin and ephemeral snow shapes melt and runoff dynamics in the Peruvian Andes '

These are the outputs of the TOPKAPI-ETH model associated with the publication 'Thin and ephemeral snow shapes melt and runoff dynamics in the Peruvian Andes'.

The main folders are MB_26, which contains the model outputs for the majority of the analysis, and MB_27 which contains the daily snow grids for the analysis of the snow cover only. They were produced by seperate model runs with the same set-up. 

These files were created by running the TOPAKPI-ETH set-up which is saved at: 10.5281/zenodo.15301957. The code to analyse these data are available on Zenodo at 10.5281/zenodo.15341457. This will allow the replication of the figures presented in the paper. 

Details of the contents of each of these files, including the variables saved and their units, can be found in the included pdf TManual_Aug2013.pdf. Links to the relevant table in this document are given below.

The files within MB_26 include:

glacier_reservoirs.ts > Volumes of snow and ice melt from every simulated glacier, and the discharges from these storages, see Table 18.3

gmb_by_area.ts > Glacier mass balance for all cells per glacier (mm w.e. cumulative)

qchan.cell.ts > Hourly discharge from selected stream locations in the catchment, in m^3 s^-^1

reservoirs.ts > Output of the reservoirs in the catchment, see Table 18.4

simulation.tpk > The run file for the model, containing all set-up selections and parameters.

TOPKAPI-ETH.log > Log file for the model during the run.

TOPKAPI-ETH.xml > Model run file. 

outputgcl > Timeseries outputs (hourly) from specific cells selected in the catchment, see Table 18.2. The cell number is associated with a grid cell location defined in the RS_CEL.asc file, this file is available in the analysis files at: 10.5281/zenodo.15341457 under Point_analysis>GRID_Data.

•   xxxx.cell (175 files, xxxx = cell number)

outputmaps > Gridded outputs at either a monthly or annual timestep saved for the whole model grid. Each file within a folder is a timestep. See Table 18.8. Note that annual files are saved per hydrological year (on the 31st October of each year) and monthly files are saved on the last day of the month. Glacier dynamics files don't save until the 2nd year.
