1. Arctic Polar Regional Climate Centre: Requirements and capacities

2. Information sources
WMO Survey on PRCC requirements and capabilities of February 2015
WMO request for potential national contributions to the proposed Arctic PRCC of December 2015

3. WMO Survey on PRCC requirements and capabilities of February 2015
For WMO RCC mandatory functions (data-, monitoring-, LRF- and training services),
-> almost 70 per cent of responding Members required this activity to be performed or co-ordinated by a Polar RCC
-> more than 75 per cent of responding Members indicated interest in contributing to PRCC mandatory functions
For WMO RCC highly recommended functions (climate prediction and projection services, non-operational data services, co-ordination functions, capacity building and R&D),
-> almost 70 per cent of responding Members required this activity to be performed or co-ordinated by a Polar RCC
-> around 60 per cent of responding Members indicated interest in contributing to PRCC highly recommended functions
