1st Permafrost_cci User Workshop of Phase 2

Saturday 17 June 2023, 9-18 h: IPA Action Group "Rock glacier inventories and kinematics (RGIK)" Workshop III

Sunday 18 June 2023, 10-12 h & Tuesday 20 June 2023, 7.30-8.30 h: CCI+ Permafrost tutorial – data access and use

Background

Within the European Space Agency (ESA), the Climate Change Initiative (CCI) is a global monitoring program which aims to provide long-term satellite-based products to serve the climate modeling and climate user community. Permafrost has been selected as one of the Essential Climate Variables (ECVs) which were elaborated during Phase 1 of CCI+ (2018-2021) and continued during Phase 2 of CCI+ (2022-2025). The two main products associated to the ECV Permafrost, Ground temperature (GT) and Active Layer Thickness (ALT), were the primary documented variables during Permafrost_CCI Phase 1 (2018–2021). Following the 2022 GCOS (Global Climate Observing System) Implementation Plan, GT and ALT are complemented by a new ECV Permafrost product: Rock Glacier Velocity (RGV).

Objectives

A series of workshops were organized during the 6th European Conference on Permafrost (EUCOP 2023) in Puigcerdà (Spain). The two tutorials of Sunday 18 June 2023 between 10 and 12 h and of Tuesday 20 June 2023 between 7.30 and 8.30 h focused on the access and use of the data generated in Phase 1 of the project, i.e. Ground Temperature, Active Layer Thickness and Permafrost Extent. The workshop of Saturday 17 June 2023 between 9 and 18 was organized by the IPA Action Group "Rock glacier inventories and kinematics" (RGIK) to discuss the background, current status, challenges and future needs of Rock glacier inventories (RoGI) and Rock glacier velocity (RGV).

ESA CCI+ Permafrost – data access and use

Workshop summary

A variety of options for Permafrost_cci datasets has been presented. This included data download as well as visualisation tools. As most of the target audience had an interest in specific regions, subsetting and location specific information retrieval was demonstrated for preselected regions as well as sites proposed by the participants. The introduction to the project and datasets also included some first higher level products (time series for annual averages) foreseen as data distribution and graphics. The options have been discussed and recommendations collected during each of the two sessions.

Workshop outcome and recommendations

Workshop participants suggested the production of regional specific higher level datasets. In addition, public access to the tutorial has been requested. Both can be achieved within the first iteration of Phase 2 of Permafrost_cci. However, a strategy for the distribution of the higher level datasets still needs to be developed.

Workshop summary

The RGIK office organized the third workshop of the IPA Action Group as a side-event of EUCOP conference in Puigcerdá. The objectives were to gather the active members of the community, summarize the achievements of the IPA Action Group and outline the goal and the workplan for the coming years. Advertised to the entire network in Spring 2023 (209 people from 29 countries), the workshop gathered 35 people. The programme was divided in three parts: 1) a reminder and summary of the RGIK objectives, tasks and achievements (international guidelines, common tools and promotion of consistent rock glacier mapping and monitoring strategies); 2) group discussions regarding the challenges and knowledge gaps to generate standardized rock glacier inventories (RoGI) and rock glacier velocity (RGV) products; 3) discussion and decision regarding the future governance of the group.

Workshop outcome and recommendations

EUCOP6 marked the end of the support of the International Permafrost Association (IPA) to RGIK as an Action Group after two periods lasting from June 2018 to June 2023. In the framework of the workshop a short document named the Puigcerdà Commitment was prepared to define the objectives of the RGIK community and lay the foundation for the transition of the Action Group to a sustainable structure as an IPA Standing Committee. The final version of the Puigcerdà Commitment has been approved by 60 people (status: July 23th, 2023). During the Council Meeting of the IPA on 21 June 2023, the request and the commitment of the RGIK Action Group were presented and discussed. The IPA Council unanimously approved the initiative, asking to be ready to transition to a Standing Committee within a year and to enlarge the scope of RGIK to rock glaciers in general. In addition to the continuation of the works done until present, the transition to a Standing Committee requires the nomination of an Executive Committee and an Advisory Board, as well as the development and approval of the by-laws, to be achieved before the next International Conference on Permafrost (ICOP) in June 2024.

Background

In the frame of the European Space Agency (ESA) Climate Change Initiative (CCI) the permafrost_cci project developed and generated a novel 23 years long climate data record of annual northern hemisphere permafrost parameters using satellite data. The products were specified based on a requirement review at the start of the project (User requirements document) building on a series of surveys within the ESA DUE Permafrost and GlobPermafrost projects. The third version of the permafrost product consists of annual ground temperature at various depths (GRD), active layer thickness (ALT) and permafrost extent (PEX). The data were released to the user community through the ESA CCI Open Data Portal.

In order to characterise the evolution of mountain permafrost globally, an IPA Action Group was launched in 2018 to manage a service dedicated to rock glacier inventories and kinematics and to promote the integration of rock glacier kinematics as a new associated parameter to the ECV Permafrost. In this context, specific guidelines to integrate kinematic information within rock glacier inventories exploiting satellite SAR interferometry were developed within permafrost_CCI and applied to eleven regional inventories worldwide (see here under Preliminary results).

The workshop will bring together the permafrost_cci project team, the Climate Research Group associated with permafrost_cci, and users of permafrost_cci products working in various application fields related to climate monitoring and modelling.
