An Intercomparison of GPS RO Retrievals with Colocated Analysis and In Situ Observations within Tropical Cyclones

Figure 4

Radial mean temperature (^∘C) intercomparisons for observations colocated with both global analysis profiles and radiosondes. The 𝑥-axis is radial distance (km) while the 𝑦-axis is vertical elevation (km). (a) Radial mean temperatures from GPS RO observations with available colocated global analysis profiles. (b) Radial mean temperatures from colocated global analysis profiles. (c) Radial mean differences between colocated observations and global analysis profiles. (d) Radial mean temperatures from GPS RO observations with available colocated radiosonde observations. (e) Radial mean temperatures from colocated radiosonde observations. (f) Radial mean differences between colocated observations and radiosonde observations. White regions in (a), (b), (d), and (e) represent where either the observations or colocated profiles are missing data.
