Campaign Activities 2011
The CICCI project brings together many institutes, field campaigns, and activities to establish common objectives and a framework under which each partner can work and contribute. Measurements will be made on Svalbard at the Holtedahlfonna Plateau; Kongsfjord fast ice; sea ice north of Spitsbergen; and near Ny-Ålesund at the Gruvebadet laboratory and Koldewey station; and at Mt. Zeppelin. Funded activities are listed below with a brief description of objectives and measurements.
NORUT/NILU VAUUAV UAV flight transects and ground-based measurements.
The Norwegian Variability of Albedo Using Unmanned Aerial Vehicles (VAUUAV) campaign is designed to a) understand albedo variability over a range of Arctic environments, and b) examine the impact of light absorbing aerosol, and in particular black carbon, deposition on the albedo of snow and ice. UAV flights will be performed over Holtedahlfonna, Kongsfjorden, and sea ice to measure variability in surface albedo. Ground-based measurements will be made in these same regions to determine surface albedo, characteristics of the snow pack, and black carbon in snow by means of thermal optical absorption.

NOAA-PMEL STADS UAS flights and ground-based measurements.
The U.S. Soot Transport, Absorption, and Deposition Study (STADS) is designed to determine sources of BC to the Arctic, deposition processes, and climate impacts. STADS UAS flights will be performed in conjunction with the VAUUAV flights to measure atmosphere aerosol properties including absorption concurrently with surface albedo. The UAS aerosol package will also be deployed on the AWI tethersonde to obtain vertical profiles of aerosol properties linking the Gruvebadet and Zeppelin stations. A more comprehensive set of measurements of aerosol properties will be made at the Gruvebadet stations including absorption to ground truth the UAS and chemical tracers to determine sources of BC-containing aerosol. In addition, light absorbing aerosols and chemical tracers within falling and freshly fallen snow will be measured. [read more...]
AWIPEV lidar measurements at Koldewey station
At the Koldewey station an Nd:Yag based “3+2” Raman lidar is located, which measures the aerosol backscatter coefficients at 355nm, 532nm and 1064nm as well as the aerosol extinction and depolarization at 355nm and 532nm. Typical resolution for aerosol evaluation are 10minutes / 60m, however a resolution of 10seconds / 7.5m is possible on request. The measurements will have a focus on the troposphere in an altitude range from 400m up to the tropopause. From the lidar data an index of refraction and a size distribution for the accumulation mode can be derived, using Mie theory. Additionally to the aerosol measurements, water vapour will be recorded up to at least 2km altitude in daylight. Optical thick clouds can only be measured with restrictions. However, additional personnel at the Koldewey station will guarantee a high data coverage for clear sky conditions. The aim of the 2011 season is to obtain a statistical representative data set of aerosol events. [read more...]
CNR-ISAC mini-lidar measurements at Koldewey station
A mini-lidar system is in operation at the Koldewey station that will provide high resolution information about the overlying structure of the atmosphere from ~50 – 500 masl. This system compliments the existing LIDAR system so that complete picture of aerosol profiles may be retrieved from the free troposphere down to sea level. Furthermore, it provides information about a critical section of the atmosphere that will be intensively investigated during the campaigns through the UAS and sonde profiling. [read more...]
CNR-IIA / CNR-ISAC spectral snow pack measurements at the Amundsen-Nobile Climate Change Tower (CCT)
The regular spectral measurements of albedo conducted by CNR-IIA near the CCT will be directly comparable with the VAUUAV measurements and will provide further ground-truthing of the UAV measurements. Three level albedo profiles collecting on the tower will provide ground long term data for placing the campaign data in context with annual variability.
CNR-ISAC / UNIFI aerosol measurements at the Gruvebadet laboratory, at the base of Mt. Zeppelin (40 masl).
Aerosol chemical, physical, and optical properties will be made by CNR-ISAC and UNIFI at the Gruvebadet Laboratory providing within boundary layer measurements close to the surface. Activities will include direct measurements (PSAP, Nefelometer, SMPS, APS, NOx) and aerosol sampling (PM10 low- and medium-volume systems, 4-stage and 12-stage impactors) for ions, metals, Elemental Carbon and Organic Carbon analysis. [read more...]
UNIFI / UNIMI balloon profiling
Sampling of aerosol vertical profiles making use of an aerostatic ballon equipped with an OPC and a 5 stage sampler, supplied by Italian groups (UNIFI in cooperation with UNIMI Bicocca) will improve the data set and provide supplementary information mainly on the chemical composition variability in the ABL.
CAMS Black Carbon aerosol measurements at Zeppelin laboratory.
The CAMS group will be operating an SP2 at Zeppelin station during April and May. The SP2 data provides information on black carbon aerosol mass concentration and size distribution.
NILU aerosol measurements at Zeppelin Observatory.
Aerosol chemical, physical, and optical properties will be made by NILU at the Zeppelin Observatory. The Zeppelin observatory is intentionally placed at an elevation of 400 m.a.s.l. in order to measure the free troposphere air mass rather than a disturbed boundary layer. [read more...]
AWI POLAR-5 Aircraft overflights of Kongsfjord / Holtedahlfonna region & R/V Lance
The Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project led by the Alfred Wegner Institute (AWI) will organize a trans-Arctic scientific research campaign flying the AWI Polar-5 aircraft from Barrow, Alaska to Longyearbyen, Norway with several stops at sites in the Canadian and Danish Arctic. The AWI campaigns have primary objectives of providing a ‘snapshot’ survey of aerosol properties and sea ice distributions in during the Arctic spring. [read more...]
AWI – Custom POLAR-5 flight planning over Ny-Ålesund, Lance
In the period from 7th of April till 6th of May several flights with different UAS are planned and from end of April till beginning of May a few POLAR 5 flights will be carried out. The AWI POLAR 5 flights will be conducted in coordination with AWIPEV ground-based activities, including the operation of LIDAR and Sun photometer measurements, operation of a second Sun photometer at Zeppelin Fjellit and tethered balloon measurements. The DigiCora is partly planned to use as receiver system for one of the UAS, outside of the standard using by radio- and ozone sounding. Additional, a few flights will be coordinated for low level intercomparison where possible with the UAS.

NPI – Long Range Transport of Black Carbon and the Effect on Snow Albedo in North-East China and in the Arctic (LOTUS)
Lotus field excursions in Ny-Ålesund area will be conducted in close co-operation with VAUUAV ground measurements. Physical characteristics of surface snow will be studied in combination with radiance measurements using Field Spec. Measurements of snow specific surface area(SSA) using DUFISS system will be conducted for different snow types. Continuous observation of albedo close to Sverdrup station, Ny-Ålesund, started in Feb 2010 using Trios Ramses sensors will be continued throughout the field campaign. [read more...]
AARI – redeployment of the Russian ‘Eleron’ UAS to Svalbard
UAS Flights will be performed by the Russian AARI using high resolution photogrammetry to map the topography of the sea ice surface.
CIRES / NOAA-GMD – Operation of the Mobile Observing System for albedo transects
The Mobile Observing System will provide high resolution ground based transects of albedo variability (with spectral components provided by integration of NILU instruments). The system also provides detailed Tskin measurements. This will enable us to to map in detail the surface albedo and Tskin within the field of view of the CCT radiometers, at the beginning and end of the campaign. As well as along the CryoWing flight tracks.
NILU – Customized FLEXPART forecasting routines with direct-ingest of CALIPSO product
FLEXPART forecasts will be run during the VAUUAV campaigns for standard antrhopogenic and biomass burning tracers. As part of CICCI we will enhance the forecast routines to include a special CALIPS product. This tracer will be initialized daily based on the CALIPSO Arctic aerosol satellite product. The output will provide a 72 hour forecast of the identified aerosol enhancement layer location. [read more...]
