CryoNet Asia Workshop in Beijing, China- Report -

CryoNet Team Meeting, Reykjavik, Iceland20-22 January 2014

Raymond Le [email protected]

The purpose of the CryoNet Asia Workshop was to continue efforts in implementing CryoNet with an emphasis on the measurement sites, observations, and issues in Asia.

Aims and need for CryoNet Classification of the CryoNet station network Selection procedure of CryoNet stations Measurement standards Data policy within CryoNet Suggestion of showcase projects for CryoNet Sustainability of CryoNet sites

The CryoNet Asia Workshop

7 Experts from the China Meteorological Administration (CMA), 23 Experts from the Chinese Academy of Sciences (CAS), 17 International experts from 14 countries

The First Global Cryosphere Watch (GCW) CryoNet Asia was hosted by the Chinese Academy of Sciences (CAS) at China Meteorology Administration (CMA) in Beijing, China from 3 to 5 December 2013.

Organisation of the Workshop

34 Presentations on 5 sessions:

Workshop Agenda

CryoNet Questionnaire

How could CryoNet help meet your national, regional or global interests?

What could you or your organization contribute to the implementation of CryoNet?

What do you see as the benefits of CryoNet: (e.g. for operational and research network operators, scientific and decision/policy making community, environmental monitoring and modelling, scientists, satellite data providers, etc.)?

What do you see as existing gaps in cryospheric observations (e.g. thematic, spatial, temporal, availability, exchange, data policy, etc.) and how might CryoNet address these?

Please prioritize CryoNet activities according your personal view (indicate HIGH/MEDIUM/LOW for each):

Please share any other thoughts for participant to consider at the meeting.

To start the GCW Asia CryoNet discussion prior to the meeting and to shareparticipant’s thoughts on the purpose, benefits, structure and scope of the network,participants were asked to answer the following questions:

CryoNet Questionnaire Summary

Break-out session on:

Potential GCW Stations

Should we focus on the “Third Pole” region or on the whole Asia?

Where to put the Asia boundary to be considered in CryoNet?

Should all stations that measure snow be part of CryoNet?

Structure of CryoNet Asia (Objectives, Tiered sites and requirements).

Climatic zones.

Sponsors.

Criteria for stations/sites inclusion in CryoNet.

Main topics addressed in this break-out session: :

Requirements for site inclusion in CryoNet

1) The station/site location is chosen such that, for the variables measured, it is regionally representative.

1) There are adequate power, communication and building facilities to sustain long term observations with greater than 90% data capture (i.e. <10% missing data).

1) The technical support provided is trained in the operation of the equipment.

1) There is a commitment by the responsible agency to long term observations of at least one of the GCW variables in the GCW focal areas.

1) The GCW observation made is of known quality and linked to the GCW Standard.

1) The data and associated metadata are submitted to one of the international cryospheric data centres (such as GTN-P, WGMS, GCOS etc. ) no later than one year after the observation is made. Changes of metadata including instrumentation, traceability, observation procedures, are reported to the responsible WDC in a timely manner.

1) If possible, data are submitted to a designated data distribution system in near-real-time.

1) Standard meteorological in situ observations, necessary for the accurate determination and interpretation of the GCW variables, are made with known accuracy and precision.

1) The station characteristics and observational programme are updated in the GCW Station Information System (GCWSIS) on a regular basis.

1) A station logbook (i.e. record of observations made and activities that may affect observations) is maintained and is used in the data validation process.

1) Observational data users have been involved in the observation design process.

2. There are adequate power, communication, and building facilities to sustain long-term observations with greater than 90% data capture (i.e. less than 10% missing data).

5. The GCW observation made is of known quality and linked to the GCW Standard.

6. The data and associated metadata are submitted to one of the international cryospheric data centres (such as GTN-P, WGMS, GCOS etc. ) no later than one year after the observation is made. Changes of metadata including instrumentation, traceability, observation procedures, are reported to the responsible WDC in a timely manner.

The 11 essential characteristics of a GCW-CryoNet Station/Site

11. Observational data users have been involved in the observation design process.

CryoNet Stations in China

(Examples extracted from the list)

Following the discussion, several Chinese stations were proposed to be part of CryoNet Asia.

CryoNet Stations in Other Asian Countries

(Missing parameters have to be collected from experts)

Other stations proposed to be part of CryoNet Asia:

Map of proposed stations

Break-out session on:

OBSERVATIONS / MEASUREMENTS / DATA

Main topics addressed in this break-out session: :

Identify needs for GCW-CryoNet activities and, based on this, building initiatives (working groups, cooperation with entwork partners (WGMS, IACS, …)

What cryosphere observing programs already have well-defined measurement standards, guidelines, and best practices (used in Asia High Elevation)?

Guidance and training for GPS measurements.

Working group to collect measurement standards, guidelines, and best practices.

Should CryoNet provide data or metadata only and what is the role of CryoNet in the context of existing world data centers?

Data policy: data have to be freely available. Are there specifications to be made? Should there be a time-span that data holder could first publish their data?

What are the main concerns on sharing data internationally?

Who will check for data quality ingested in GCW?

Action Plan

Jan.2014Jeff KeyUpdate GCW-IP by replacing the term “Supersite”by “Integrated Site”.

10

Jan.2014Jeff KeyUpdate GCW-IP to include a mechanism within GCW to coordinate work of GCW Working Groups and GCW-R-WGs.

9

Jan.2014Jeff KeyUpdate GCW-IP to include Himalaya, Pamir and Tien Shan in the Third Pole definition of CryoNet Asia (wider than it is now).

8

These are at least partly done in the latest IP version. More discussions on that point are requiered.

Jan.2014Jeff KeyUpdate GCW-IP to better define role of the Third Pole in GCW

7

Are we all agreed that AWSs should be part of CryoNet?

Sep.2014Members of GCW-R-WG

Include AWS in the CryoNet Asia.6

Mar.2014SecretariatWrite a letter to countries’ Permanent Representative for WMO to reaffirm the GCW focal point and to seek support for GCW and CryoNet.

5

Mar.2014SecretariatCompile information on proposed stations of CryoNet Asia.

4

Mar.2014Cunde Xiao & Barry Goodison (with help from Secretariat)

Define a formal procedure to nominate experts to GCW-R-WG

3

Jun.2014Cunde Xiao (with help from Secretariat)

Within GCW-R-WG in RA II, establish a Working Group on Practices, i.e., membership, work plan.

2

Should GCW be organized by WMO regions?

Jun.2014Jeff Key & Arni Snorrason (with help from Secretariat)

Establish Regional Working Groups (GCW-R-WG) (according to WMO Regions), i.e., membership, work plans, etc.
