Atmospheric and oceanic forcing are available from the 2019-2020 Multidisciplinary Drifting Observatory
742
742
for the Study of Arctic Climate (MOSAiC) expedition :cite: `Clemens-Sewall24 `. The atmospheric forcing is
743
743
available minutely and the oceanic forcing is available daily. These data are based on observations from
744
- a collection of drifting ice floes in the Arctic Ocean. MOSAiC
744
+ a collection of drifting ice floes in the Arctic Ocean. MOSAiC consisted of two drift experiments,
745
+ in which the R/V Polarstern was moored to a drifting ice floe and continuous observations were made. The
746
+ first drift started in October 2019 North of the Laptev Sea (85.4N, 129.2E) and ended in July 2020 in
747
+ the Fram Strait (79.2N, 2.6W). The second drift was from August to September, 2020 in the vicinity of
748
+ the North Pole (approximately 88.6N, 110.6E).

750
+ Atmospheric forcing fields from :cite: `Clemens-Sewall24 ` consist of 2-m air temperature (K), 2-m
751
+ specific humidity (kg/kg), 2-m wind velocity in the u and v directions (m/s), downward solar radiation
752
+ (:math: `W/m^2 `), and downward longwave radiation (:math: `W/m^2 `). For the first drift, snowfall rate
753
+ (:math: `kg/m^2 /s`) is also available. Oceanic forcing fields consist of mixed layer salinity (PSU),
754
+ mixed layer depth (m), turbulent heat fluxes over the halocline and thermocline (:math: `W/m^2 `),
755
+ mixed layer temperature (K), ocean-ice friction velocity (m/s), and sea ice drift speed (m/s). Note,
756
+ icepack's driver currently lacks a mechanism to use the ocean-ice friction velocity and/or sea ice
757
+ drift speed in the thermodynamics calculations. Additionally, caution should be used when using the
758
+ ocean mixed layer temperatures directly because for much of the experiment icepack's parameterization
759
+ of the ocean mixed layer freezing point differs from the true freezing point by ~0.5 C.
760

761
+ MOSAiC data are available exclusively as MDF-formatted netCDF files (see :ref: `init `).
