[IGSMAIL-8076] AGU sessions focused on FORMOSAT-7/COSMIC-2 Results

[John Braun]

Dear Colleagues,

We would like to draw your attention to two sessions at the AGU 2021 Fall
Meeting related to the FORMOSAT-7/COSMIC-2 mission and GNSS-Radio
Occultation in general. As the F7/C2 mission transitions into Full
Operational Capability (FOC) we look forward to an exciting collection of
presentations highlighting progress in RO science. This year's Fall AGU
Meeting will be in-person and virtual in New Orleans.

Deadline for abstract submission is August 4,

SA012. Impacts and Results of the FORMOSAT-7/COSMIC-2 Mission for Space
Weather Operations and Research
<https://agu.confex.com/agu/fm21/prelim.cgi/Session/124425>

FORMOSAT-7/COSMIC-2 (F7/C2) is a joint satellite program between the Taiwan
and the United States governments providing space weather data for
operational and research communities. Each satellite has a mission payload,
a Tri-GNSS Radio occultation System (TGRS) instrument, as well as two
science payloads, an Ion Velocity Meter (IVM) and Radio Frequency Beacon
(RFB). The F7/C2 mission provides unprecedented data coverage at low
latitudes from altitudes ranging from 90 to 550 km and across all local
times. Products support ionospheric forecasting and space weather research
at scales ranging from global ionospheric specification to small scale
ionospheric scintillation/irregularities within the low-latitude Equatorial
Ionospheric Anomaly (EIA) region. Presentations related to use of F7/C2
data products for both operational and scientific applications as well as
comparisons and joint observations with existing satellite missions, such
as NASA ICON, GOLD and ESA SWARM, and assimilation/modeling works in
connection to application of F7/C2 data are also solicited.


A084. Neutral Atmosphere Science Advances Using GNSS Radio Occultation
<https://agu.confex.com/agu/fm21/prelim.cgi/Session/124333>
Global Navigation Satellite System Radio Occultation (GNSS-RO) observations
provide near-vertical profiles of refractivity, temperature, and moisture
from the boundary layer to the stratosphere with high vertical resolution,
global coverage, and all-weather capability. The value of these
observations to the atmospheric science community has been demonstrated
over the past two decades. RO measurements are routinely assimilated into
numerical weather prediction models without bias correction and are well
suited to long-term climate monitoring. This session aims to explore recent
scientific advancements using GNSS-RO data in the neutral atmosphere. An
emphasis will be placed on science studies using data from the
FORMOSAT-7/COSMIC-2 (C2) constellation. The C2 constellation provides a
unique opportunity to study the lower latitude neutral atmosphere, owing to
high signal-to-noise ratio and dense sampling throughout the tropics.
Science utilizing other recent missions such as Sentinel-6, GRACE-FO, and
commercial RO providers is also sought.
