Abstract:
Merged model Data Files (MMDFs) for ECCC-CAPS are available for the whole period from February 2018 to December 2018. Prior to the 28th of June 2018 CAPS was uncoupled and run with the GEM version 4.9.2. After the 29th of June 2018 CAPS was coupled with the Regional Ice and Ocean Prediction system (RIOPS) and run with the GEM version 4.9.4. Atmospheric Lateral Boundary Conditions (LBCs) and initial conditions (ICs) are from ECCC Global Deterministic Prediction System (GDPS). Initial surface fields are from the Canadian Land Data Assimilation System (CaLDAS). The CAPS timeseries are produced for a beam of 7 x 7 grid-points centred on each of the twelve land-based Arctic observatories listed in Table 1. Timeseries up to 48 hours leadtime are made available for the daily runs initialized at 00 UTC. The data is archived with a time frequency of 7.5 min, equivalent to five timesteps of 90 s each.
