Selected papers published in Advances in Space Research and Life Sciences in Space Research, fully refereed journals with no deadlines open to all submissions in relevant fields.

The Climate and Cryosphere (CliC) project is one of the core projects of the World Climate Resarch Programme (WCRP), serving as the focal point for climate science related to the cryosphere, its variability and change, and interaction with the broader climate system.

CliC is now launching an open call for nominations for chairmanship. Self-nominations are encouraged. Please fill in this form and it send to  no later than April 16th 2021. If you have questions, please contact present co-chairs Fiamma Straneo or James Renwick.

Abstract submission is now open for the 16th IGAC Conference, to be held virtually starting September 12th, 2021. The theme of this conference is Atmospheric Chemistry from a Distance: Real Progress through Virtual Interaction

For the 2021 virtual conference, IGAC’s scientific program will center its scientific program around its current working groups and activities.  This will highlight the exciting work being done as part of IGAC, grow the networks of these working groups and activities, and expose new scientists to the year-round work IGAC does. IGAC will also have an open science session for atmospheric chemistry research that does not fit into any current working groups or activities. We hope this will expose any gaps in IGAC’s current activities and serve as a poll for the atmospheric community on the next big questions in atmospheric chemistry. 

Abstracts are open for submission here and are due May 1st, 2021. You may modify abstracts submitted for the delayed Manchester 2020 IGAC conference or delete and submit a new abstract. 

The conference will take place the week of September 12, 2021. An Early Career Research Programme will take place the week before the main conference. A link to register your interest in this program is at the bottom of the abstract submission link.  To register for the conference without submitting an abstract, click here.

US CLIVAR seeks comments and input from the science community on the draft white paper “Summarizing Weather, Climate, and Earth System Observational Data Sharing Needs for Research and Education.”

The document is intended to (1) raise community awareness of US federal agency decisions to restrict access and sharing of observational data sets through recently established commercial data buys and (2) articulate data needs and benefits of federal commitments to free, open, and unrestricted observational data access and exchange for scientific research and education.

Developed by a writing team charged by the US CLIVAR Scientific Steering Committee, the draft white paper incorporates inputs received through consultation with members of the US CLIVAR organization as well as feedback from members of the scientific community collected through two Town Halls. Suggestions from this open review period will be considered in preparing the final publication.

Download the draft white paper and enter your comments here (Google d oc). The document is intentionally concise, so it is a quick read at just eight pages in length. Please provide comments and suggest text changes on the current draft by Monday, March 15, 2021.
