Exploring earth's atmosphere with radio occultation: contributions to weather, climate and space weather (2011, neutral): “Gobiet and Kirchen-gast (2004), Kuo et al. (2004), and Gobiet et al. (2007) show that the inversion errors associated with the observational noise, ad hoc optimization process and the choice of ancillary data (e.g. climatology) can be signiﬁcant above 35 km in the stratosphere, especially at high…”
GPS radio occultation with CHAMP and GRACE: A first look at a new and promising satellite configuration for global atmospheric sounding (2005, methodology): “The measurements of CHAMP and SAC-C brought significant progress to the GPS occultation technique (e.g. Hajj et al., 2004; Kuo et al., 2004; Wickert et al., 2004b).”
GPS radio occultation for climate monitoring and change detection (2011, methodology): “…performed in reference to ECMWF analysis fields, provided observational error estimates for RO parameter profiles from bending angle to temperature [Scherllin‐Pirscher et al., 2011a] confirming and extending former studies [Kuo et al., 2004; Steiner and Kirchengast, 2005; Steiner et al., 2006].”
Diagnosis of an Intense Atmospheric River Impacting the Pacific Northwest: Storm Summary and Offshore Vertical Structure Observed with COSMIC Satellite Retrievals (2008, methodology): “Detailed descriptions of the GPS RO technique and data processing procedures can be found in Kursinski et al. (1997) and Kuo et al. (2004), respectively.”
Comparison of GPS radio occultation soundings with radiosondes (2005, background): “…measurements (that drift as they ascend through the atmosphere) while satellite soundings, including RO soundings, represent averages over finite volumes of the atmosphere, and hence there are significant representativeness issues when the two types of soundings are compared [Kuo et al., 2004].”
Estimates of the precision of GPS radio occultations from the COSMIC/FORMOSAT‐3 mission (2007, background): “Processing of the observed OL RO signals from SAC-C was briefly described by Sokolovskiy et al. [2006a]. A technical goal of COSMIC is to provide 2500 high quality GPS RO soundings per day from orbit altitude down to within 1 km of the surface.”
COSMIC‐2 Radio Occultation Constellation: First Results (2020, methodology): “The SD of differences between two data sets is a common method of comparing the random errors of different data sets (Kuo et al., 2004).”
Comparing radiosonde and COSMIC atmospheric profile data to quantify differences among radiosonde types and the effects of imperfect collocation on comparison statistics (2010, methodology): “…the times and locations of the radiosonde balloon launch and COSMIC occultation point, i.e., the point on Earth's surface to which the retrieved refractivity profile is assigned, which is generally located at 2–4 km above the surface along the refractivity profile trajectory [Kuo et al., 2004].”
The COSMIC/FORMOSAT-3 Mission: Early Results (2008, methodology): “Before the inversion, the CHAMP raw signals were subject to screening for obvious PLL tracking errors (Kuo et al. 2004) and truncation.”
Error analysis of Abel retrieved electron density profiles from radio occultation measurements (2010, methodology): “Lei et al. (2007) compared COSMIC EDPs with ISR observations at Millstone Hill (middle latitude) and Jicamarca (magnetic equator) and found that the agreement is better at Millstone Hill than Jicamarca, which is also consistent with our simulation results.”
