• SNOW/ICE – ATMOSPHERE INTERACTION Energy balance in the surface layer – Physico-chemical processes at the surface involving aerosols

and snow. Fluxes of moisture, trace gases, pollutants. Snow-melting process. Surface Albedo. Role played by cloudiness and PBL characteristics.

• PLANETARY BOUNDARY LAYER INVESTIGATIONS Characterize the climatology of the basic meteorological parameters. Thermal and

dynamical characteristics of the turbolence (in particular during the season transition periods). Dependence on cloud cover. Interaction between local and synoptic circulation

Topics measurements on CCT can contribute to deepen

• PERMAFROST AND COUPLING WITH THE ATMOSPHERE Fluxes of heat and moisture in the active layer. Permafrost temperature profile (up to –30

m). Closure of the energy budget at the surface. Understanding and quantifying the buffering effect of the system permafrost-vegetation. Climate change impacts of climate change on permafrost and active layer.

• AEROSOL-CLOUD-CLIMATE INTERACTION Aerosol chemical and physical characterization at the ground. Precipitation chemistry.

Aerosol thin clouds vertical profile into the troposphere. Closure tests between radiative transfer models and BSRN measurements. Evaluation of aerosol direct effects (local and regional scale).

• UV RADIATION Spectral measurements in the range between 300 and 400. UV flux dependency from

cloudiness conditions.

Scheduled plan for spring/summer 2010 campaign

Largest part of the material transported at Ny Alesund by ship before end of 2009.

Installation of instrumentation at the beginning of March

Start of the field campaign March 15

End of the campaign beginning September

Usually 2-3 researchers on field. Full plan to be developed considering other scheduled and ongoing (ARCFAC ?) activities

All to be carefull consider looking our budgets and new costs for LYR-NYA transport, unexpected events, etc.

Idea is to remain most part of instruments as possible legacy for a common infrastructure

Planned measurements

Particle size distributionParticle size distribution (DMA + APS TSI instruments + a TSI UCPC)

Aerosol scattering properties (1 Radiance Research M903 nephelometer + hopefully a TSI from IOPAS)

Aerosol absorption coefficient (1 Radiancde Reserach PSAP photometer)

Aerosol Integral chemical composition (2 PM10 Tecora sampler, 1 with 15 filters for automatic change)

Aerosol size-segregated composition (2 Dekati DLPI 13 stages + 1 Dekati 4 stages + 1 Andersen 8 stages)

Organic compounds (OC-EC HV)OC-EC HV) ((passive sampler + 1 TSP MV Tecora sampler)

Planned measurements

Heavy metals (PM10 MV sampler + 6 stage HV sampler)

NOx (continuous measurements with an NOx analyzer + denuders system)

HONO analyzer

A co-located (with flux measurements) integrated system for Surface Energy balance evaluations

Measurements more that at Grouvenbadet and CCTVertical aerosol profiles (with the minilidar hosted by AWI)

Snow Reflectance characteristics (around NYA with a FieldSpec FR spectroradiometer)

Sensor Network for Oceanography in Shallow Water - Kongsfjord experiment (SNOW)

Remote controlled underwater units

Atmosferic measurement at the interface
