Ice station meteorological data from the Arctic Ocean 2018 expedition

Jutta Vüllers, Ian Brooks, Peggy Achtert, John Prytherch

This dataset contains meteorological data — air temperature, near-surface air temperature profiles, relative humidity, surface temperature, near-surface wind profiles, shortwave and longwave radiation components, wind speed and wind direction — measured at a station on the ice floe during the joint Arctic Climate Across Scales (ACAS) and Microbiology-Ocean-Cloud Coupling in the High Arctic (MOCCHA) projects — both part of the Arctic Ocean 2018 (AO2018) expedition to the High Arctic.

AO2018 took place in the Arctic from 1 August until 21 September 2018.

Data description

1 minute averages of mean meteorological variables from a 15m mast installed on the sea ice:

• near-surface air temperature and wind speed profiles
• relative humidity
• surface temperature
• up- and down-welling shortwave and longwave radiative flux components
• wind speed
• wind direction

Comments

Measurement system

Measurements were made on a 15-m tall mast installed on the sea ice, approximately 300 m from the Oden. Mean temperature profiles were obtained from T-type thermocouples installed in aspirated radiation shields at 0.80, 1.55, 3.05, and 8.80 m to measure the near-surface temperature profile. A final thermocouple was installed at the snow/ice interface to measure ice surface temperature.

NRG Type-40 cup anemometers were installed at 0.65, 1.45, 2.86, 6.65, and 13.25 m to measure the near-surface wind speed profile. Mean wind and direction are obtained from a Metek USA-100 sonic anemometer installed at the top of the mast (15.55 m).

A Väisälä HMP-110 T/RH probe was installed in an aspirated radiation shield at the top of the mast (15 m) to give a reference temperature and relative humidity. Pairs of Kipp & Zonen CMP22 pyranometers and CGR4 pyrgeometers were installed approximately 50 m from the mast to measure up- and down-welling solar and infrared radiative fluxes. A Heitronics KT15-II infrared temperature sensor measured the surface skin temperature immediately below the radiometers.

All measurements are given as 1-minute averages.

Quality control

There are gaps in the time series resulting from power failures, problems with the data logging system, and icing of instrumentation.

The expedition

Data were collected during the Arctic Ocean 2018 expedition on board the Swedish icebreaker Oden, which was organized by the Swedish Polar Research Secretariat.
