Abstract: The Greenland Climate Network (GC-Net) consists of 31 automatic weather stations (AWSs) at 30 sites across the Greenland Ice Sheet. The first site was initiated in 1990, and the project has operated almost continuously since 1995 under the leadership of the late Konrad Steffen. The GC-Net AWS measured air temperature, relative humidity, wind speed, atmospheric pressure, downward and reflected shortwave irradiance, net radiation, and ice and firn temperatures. The majority of the GC-Net sites were located in the ice sheet accumulation area (17 AWSs), while 11 AWSs were located in the ablation area, and two sites (three AWSs) were located close to the equilibrium line altitude. Additionally, three AWSs of similar design to the GC-Net AWS were installed by Konrad Steffen's team on the Larsen C ice shelf, Antarctica. After more than 3 decades of operation, the GC-Net AWSs are being decommissioned and replaced by new AWSs operated by the Geological Survey of Denmark and Greenland (GEUS). Therefore, making a reassessment of the historical GC-Net AWS data is necessary. We present a full reprocessing of the historical GC-Net AWS dataset with increased attention to the filtering of erroneous measurements, data correction and derivation of additional variables: continuous surface height, instrument heights, surface albedo, turbulent heat fluxes, and 10 m ice and firn temperatures. This new augmented GC-Net level-1 (L1) AWS dataset is now available at https://doi.org/10.22008/FK2/VVXGUT (Steffen et al., 2023) and will continue to be refined. The processing scripts, latest data and a data user forum are available at https://github.com/GEUS-Glaciology-and-Climate/GC-Net-level-1-data-processing (last access: 30 November 2023). In addition to the AWS data, a comprehensive compilation of valuable metadata is provided: maintenance reports, yearly pictures of the stations and the station positions through time. This unique dataset provides more than 320 station years of high-quality atmospheric data and is available following FAIR (findable, accessible, interoperable, reusable) data and code practices.

A COMPREHENSIVE COOPERATIVE AGREEMENT ESTABLISHED THE EARTH SYSTEM SCIENCE INTERDISCIPLINARY CENTER (ESSIC) IN 1999. ESSIC IS INTENDED TO SERVE AS A MEANS TO INCREASE THE EFFECTIVENESS OF RESEARCH ANDTEACHING THROUGH CLOSE COLLABORATION BY BOTH PARTIES AND SERVE AS A MEANS TO TRAIN PERSONNEL FOR RESEARCH IN EARTH SYSTEM SCIENCE. ALL APPOINTEES TO ESSIC SHALL PARTICIPATE IN THE EDUCATIONAL MISSION OF THE UNIVERSITY BY ADVISING GRADUATE STUDENTS IN ADDITION TO CONDUCTING COLLABORATIVE RESEARCH. THE PURPOSE OF THIS PROPOSAL IS TO REQUEST A CONTINUATION OF THE COOPERATIVE AGREEMENT ENABLING THE UNIVERSITY OF MARYLAND TO CARRY OUT A COLLABORATIVE RESEARCH PROGRAM WITH GODDARD EARTH SCIENCES WITH THE GOAL OF FURTHERING ITS MISSION: THE EARTH SCIENCES DIVISION ATNASA GODDARD SPACE FLIGHT CENTER PLANS ORGANIZES EVALUATES AND IMPLEMENTS A BROAD PROGRAM OF RESEARCH ON OUR PLANET'S NATURAL SYSTEMS AND PROCESSES. MAJOR FOCUS AREAS INCLUDE CLIMATE CHANGE SEVERE WEATHER THE ATMOSPHERE THE OCEANS SEA ICE AND GLACIERS AND THE LANDSURFACE. GSFC HAS FOR OVER 50 YEARS BEEN A LEADER IN EARTH SCIENCE RESEARCH AND TECHNOLOGY DEVELOPMENT. ESSIC SEEKS TO BUILD EVEN STRONGER PARTNERSHIPS WITH GODDARD IN THE AREAS OF METEOROLOGY OCEANOGRAPHY TERRESTRIAL PHYSICS CLIMATE RESEARCH CHEMISTRY OF THE EARTH'SATMOSPHERE AND SATELLITE RESEARCH. WE ENVISION THIS LATEST COOPERATIVE AGREEMENT AS A MEANS TO INCREASE THE EFFECTIVENESS OF RESEARCH AND TEACHING THROUGH CLOSE COLLABORATION BY BOTH PARTIES AND SERVE AS A MEANS TO TRAIN PERSONNEL FOR RESEARCH CAREERS IN EARTH SYSTEM SCIENCE. THIS PROPOSAL SUMMARIZES CURRENT RESEARCH THEMES THAT CAN BE CARRIED OUT JOINTLY BY NASA/GSFC AND ESSIC RESEARCHERS OVER THE NEXT FIVE YEARS AS WELL AS PROSPECTIVE RESEARCH OPPORTUNITIES LAYING A VISION INTO WHAT CAN ACCOMPLISHED IN SCIENCE THROUGH THIS COOPERATIVEAGREEMENT. AT THE DISCRETION OF NASA/GSFC RESEARCHERS AT ESSIC CAN ENGAGE IN A LARGER PORTFOLIO OF AREAS OF INTEREST TO GODDARD E.G. BIOSPHERIC SCIENCES OCEAN ECOLOGY TERRESTRIAL INFORMATION SYSTEMS. UMD IS OFFICIALLY CLASSIFIED BY NASA AS A AANAPISI (ASIAN AMERICAN NATIVE AMERICAN PACIFIC ISLANDER SERVING INSTITUTION); THE UNIVERSITY ALSO HOUSES>12% OF AFRICAN AMERICAN AND>10 %HISPANIC STUDENTS PROVIDING A VERY RICH POOL OF UNDERREPRESENTED GROUPS IN STEM TO THIS COOPERATIVE AGREEMENT. WE PROPOSE TO BOOST THE PARTICIPATION OF THESE STUDENTS IN RESEARCH THROUGH INTEGRATED RESEARCH EDUCATION AND INTERNSHIP EXPERIENCES THAT CAN BE OF BENEFIT TO NASA/GSFC AND TO THEIR FUTURE CAREERS IN STEM FIELDS.
