GCW Activities

(what is GCW doing, or what’s happening that wouldn’t otherwise happen)

Fundamental contribution to

GEOSS

;

refining

cryosphere

observational

requirements for WIGOS OSCAR ;network of surface observations, with

"CryoNet“ at its core;

collating/establishing

measurement guidelines

and best practices;

engaging in and supporting

intercomparisons of instruments and (satellite) products

, e.g.,

GCW Snow Watch

(and SnowPEx);

SPICE

e

nable

access to data and metadata

through GCW portal

;

Use the WMO data regulatory framework to enable the development and implementation of

data/metadata standards

contributing

to WMO’s space-based capabilities database (with PSTG);

producing

unique hemispheric products

, e.g., “snow anomaly trackers

”;

engaging in

historical data rescue

(e.g., snow depth);

building a

glossary of

cryospheric

terms

;

CryoNet

network of

cryospheric

in-situ

observations

.

extensive monitoring through GCW (standardized) practices;

cryospheric

data

for improved process

understanding

and modelling;

calibration

and validation data for satellite data;linking cryospheric ground truth observations to cryospheric models;training.

WMO Rolling Review of Requirements

https://www.wmo.int/pages/prog/www/OSY/GOS-RRR.htmlReview of technology free requirements for observations within each area of applicationReview of observing capabilities (existing, planned) of observing systems (surface, space based)Critical review of the extent to which the technology deliver the requirementsStatement of Guidance: Inform on the extent to which the requirements are met by the identified systemsInforms the dialogue with the observing system developing agencies, influencing future research

Feasibility and affordability

Application Areas

Global NWP;High resolution NWP;Nowcasting and very short range forecasting;Subseasonal to longer term prediction;Forecasting atmospheric composition;Monitoring atmospheric composition;Provide atmospheric composition information to support services in urban and populated areas;

GCW DATA PORTAL

Engagement with Arctic Data CommitteeExchange cryosphere data, metadata, information and analyses among a distributed network of providers and users.

The

GCW Data Portal is part of WIS

,

a

Data Collection and Production Centre

and

is interoperable with data

centres

.

YOPP data management builds on GCW data management

Collaboration and cooperation with partners is

essential

to successfully

conduct

GCW activities at the international, regional and national

levels.
