Towards a better harmonization of snow observations, modeling and data assimilation in Europe

Towards a better harmonization of snow observations, modeling and data assimilation in Europe

2018-10-30 - 2018-10-31
Conference Center, Hotel Gellért - 2 Szent Gellért tér
Budapest, Hungary

This workshop will be built around eight sessions:

1. Intercomparison of measurement methods , remote sensing product and assessment of their errors
Chair: Leena Leppänen, Nacho Lopez Moreno

Nowadays a wide range of instruments and products are available to measure the extent, water mass, precipitation, physical, and chemical properties of snow. Comparison of these instruments is important for producing consistent observations. This session will involve presentations about the intercomparison of methods and techniques to measure the properties of snow and assess measurement errors.

2. Recommendations on measurement methods and instrumentation
Chair: Ladislav Holko, Charles Fierz

Measurement or indirect assessment of snow characteristics comprises a variety of approaches which are applied by different groups or institutes around the world in slightly different ways. This results in differences that limit the comparability of these measurements and indirect assessments. This session aims to explore efforts of standardization of the measurement protocols, recommendations on the use of instruments, and other methods of acquisition of snow characteristics and homogenization of imperfect observations.

3. Snow observation reporting and dissemination
Chair: Samantha Pullen and Ghislain Picard

Observations of snow properties are of vital importance for a wide range of applications, including operational services and research applications. To fully exploit valuable observational data, there must be a harmonised approach to observation reporting practices, data formats, and dissemination. Data must be freely available with a timeliness that satisfies user requirements. This session will discuss topics related to harmonised approaches to observations of snowpack properties and initiatives to make these observations available and useable by the international community for operational and research purposes. 

4. Snow data assimilation methods in NWP, hydrology, and other disciplines
Chair: Ekaterina Kurzeneva, Carlo De Michele

This session is about how snow observations are used through data assimilation techniques to improve forecasting for different applications. 

5. Representation of errors in NWP, hydrological and climate models
Chair: Vera Potopová , Martin Lange

This session aims to address different topics related to errors and the impact of estimates in data assimilation systems and on climate applications, as well as the application of snow observations in climate and other models.

6. Intercomparison of snow models and future of snow modeling across disciplines
Chair: Marie Dumont, Jürgen Helmert

Continuous estimates of the snow state from numerical model predictions are still limited by uncertainties in meteorological forcing data and model structural problems for snow processes in land surface models. Three major classes of snowpack models are employed for various applications: single-layer snow models, schemes of intermediate complexity, and detailed snowpack models, which differ in the description and the parameterization of the properties inside the snowpack and the related processes. The choice of the model complexity level is generally guided by the foreseen application. For instance, in the case of avalanche hazards forecasting, a detailed description of the the snowpack physical properties is required and thus a multi-layer model is to be preferred. This session aims to review existing snow models used in numerical weather prediction and climate models, hydrology, and for the avalanche hazards forecasting. 

7. Actions and methods for training snow scientists and observers
Chair: David Christian Finger, Martin Schneebeli

Training in measuring snow properties is extremely important to obtain data of high quality. As the measurement methods require either somewhat subjective classification skills and / or very specific measurement techniques, initiatives to train these competencies have been promoted internationally at different levels and operational contexts. 

8. Harmonization strategies across international organizations and other activities
Chair: Patricia De Rosnay, Ali Nadir Arslan

This session will discuss common synergies and interactions on harmonization of snow measurements within existing international initiatives and programmes with the contributions of the COST Action on HARMOSNOW. We will also discuss how to move forward to harmonized snow observations in the future for both in-situ and satellite measurements.

Registration for this event is mandatory as spaces are limited.
