ESA Water Vapour CCI User workshop

Dates: 14-18 June 2021
Location: Online meeting
Abstract Submission Deadline: 5 May 2021

The Water Vapour Climate Change Initiative (WV_cci) is a project of the European Space Agency (ESA) with the overall goal to generate climate data records (CDRs) of atmospheric water vapor for use in climate applications. The project develops, validates, and releases quality-controlled, long-term CDRs of total column water vapor (TCWV) and water vapor profiles in the stratosphere (2D), as well as a five-year data record of water vapor profiles in the troposphere and lower stratosphere (3D).

The aim of the workshop is to bring together the broader water vapor community, including those interested in the generation of water vapor CDRs and data users (such as climate modelers and NWP researchers) in order to discuss the most recent scientific applications and challenges in processing and using water vapor CDRs.

Topics of the workshop include:

      • Discuss challenges related to the generation of water vapor CDRs.
      • Show-case climate user applications of water vapour CDRs (with focus on WV_cci CDRs).
      • Collect and update user requirements for atmospheric water vapor.
      • Present and discuss results from climate analysis, climate applications, and process studies using water vapour CDRs.

2nd Climate Observation Conference

Dates: 30 August–3 September 2021
Location: Online meeting
Abstract Submission Deadline: 14 June 2021

The Global Climate Observing System (GCOS), with the World Climate Research Programme (WCRP), and supported by European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), will be holding a conference that aims to assess how well the current global climate observing system supports current and near-term user needs for climate information. The outputs will provide inputs into the next GCOS implementation plan, which will make recommendations to meteorological networks, major observing systems, and satellite agencies.

Sustained observations of the global climate system are essential for understanding, predicting, mitigating and adapting to climate change. Progress in understanding and attributing climate change has been largely based on climate observations. In order to continue improving this understanding, it is vital to make further progress towards achieving a fully implemented, sustainable, global observing system for climate.

Water  Special Issue: “Hydrological Extremes in a Warming Climate: Nonstationarity, Uncertainties and Impacts”

Special Issue Editors:
Dr. Rajesh R. Shrestha (University of Victoria), Dr. Mohammad Reza Najafi (Western University)

Paper submission deadline: 31 April 2021

The journal Water (IF: 2.544, ISSN 2073-4441) will feature a Special Issue on “Hydrological Extremes in a Warming Climate: Nonstationarity, Uncertainties and Impacts”. The topics covered by this special Issue will include but not limited to the following:

      • Analysis of historical variability and trends in streamflow extremes (e.g., peak flow, low flow, timing) and teleconnections to hydroclimatic drivers
      • Model based studies on future changes in hydrologic extremes and the role of internal variability and anthropogenic forcings
      • Development and application of nonstationary methods for the evaluation of hydrologic extreme events
      • Evaluation of uncertainties of extreme value projections
      • Methods to quantify flood and drought risks
      • Implications of changes in hydrologic extreme events on water resources management

Advances in Atmospheric Sciences  Special: Cloud–Aerosol–Radiation–Precipitation Interaction: Progress and Challenges

Lead Editor:
Chuanfeng Zhao (College of Global Change and Earth System Science, Beijing Normal University)

Manuscript Submission Deadline: 31 May 2021

This special issue will showcase recent and ongoing research progress in (1) cloud observation techniques and remote sensing inversion algorithm development for cloud properties, and (2) cloud–aerosol–radiation–precipitation interactions and their potential underlying mechanisms. The compilation of research papers in this special issue is expected to improve our understanding of cloud properties and cloud-process-associated issues, as well as assist with the development of cloud-associated parameterization in weather and climate models.

Special Collection on “Advances in Scaling and Modeling of Land-Atmosphere Interactions”

Special Section Organizers:
David S Schimel (NASA JPL), Benjamin Poulter (NASA GSFC), Natasha Stavros (NASA JPL), Phil Townsend (University of Wisconsin), Nancy Glenn (Boise State University)

Deadline: 31 December 2021

Earth’s surface and its biological organisms exchange heat, momentum, carbon, and water with the overlying atmosphere at a multitude of scales. However, capturing those interactions across scales remains a challenge for observing systems and Earth system models. Here, the editors solicit papers highlighting recent investigations from land-atmosphere field campaigns, including observational analyses, tests of theoretical approaches to scaling or modeling these processes, and model-based evaluation and diagnostic studies.
Papers can be submitted to JGR: Biogeosciences, JGR: Atmospheres, Earth and Space Sciences, or Journal of Advances in Modeling of Earth Systems (JAMES). The latter two are gold open-access and the first two have open-access options.

Water  Special Issue “Hydrological Cycle and Land-Atmosphere Interactions: From Evapotranspiration to Precipitation”

Special Issue Editors:
Prof. Dr. Jiangfeng Wei (School of Atmospheric Science, Nanjing University of Information Science & Technology) and Prof. Dr. Min-Hui Lo (Department of Atmospheric Sciences, National Taiwan University)

Deadline: 31 December 2021

In this Special Issue, studies are sought that investigate the facts and mechanisms related to the processes from surface evapotranspiration to precipitation. The topics covered by this Special Issue will include but not be limited to the following:

  • Land–atmosphere interactions and the hydrological cycle;
  • Atmospheric boundary layer processes, cloud physics, and precipitation;
  • Atmospheric moisture transport and tracking;
  • Impact of human activities on the hydrological cycle;
  • Aerosol–cloud–climate interactions.
