8th International Radio Occultation Working Group Meeting - IROWG-8
Hosted by NOAA / UCAR
7 April, 2021 to 14 April, 2021
Washington, D.C. Area

An international workshop for atmospheric sensing by radio occultation methods and the use of radio occlusion data in atmospheric physics, meteorology, and climate.

The joint 8th IROWG Workshop is an opportunity for the GNSS RO community to present and discuss the latest scientific, technical, and programmatic developments in the area. The objective of the joint workshop is to improve the management and use of RO measurements for operational and science applications.

Nominally taking place April 7-14, 2021 in Virginia at the National Conference Center located in the scenic hills of Loudoun County, Virginia just 45 minutes away from Washington D.C.

The IROWG Planning Committee is closely monitoring, in aligment with federal, state and local guidance and The Centers for Disease Control and Prevention (CDC) guidance related to the Coronavirus (COVID-19).  We continue to plan for the IROWG 2021 Workshop. If there are any changes to plans for the meeting, we will give immediate notice.

We are collecting feedback to help with the planning process of IROWG-8. Please complete this very short survey regarding attendance to the Workshop.

Topics to be discussed at the workshop will include:

  1. Status and assessments of “agency-led” GNSS RO missions (e.g., COSMIC-2, FY-3C, Metop, PAZ)
  2. Status and assessments of commercial missions
  3. Climate applications
  4. Improving the impact of GNSS RO measurements in operational NWP and climate reanalyses
  5. Improving GNSS RO retrievals in the lower troposphere and upper stratosphere
  6. Estimating the impact of future GNSS RO missions with OSSEs and the Ensemble of Data Assimilations approach
  7. Ionospheric retrievals and space weather applications 
  8. New innovations and applications of RO data
  9. Student research session

General Workshop Format

With about 125 participants it is planned to have a workshop with no parallel sessions, high-visibility of posters and ample informal possibilities to enter into scientific discussion.
