Short summary
We analyze space-borne observations of simultaneous vertical profiles of precipitation, cloud layers, and temperatures, and find that about 80–90 % of cloud tops globally reach or are below the level of least stability. Since water vapor is limited at these low temperatures, this height may be a more important constraint on cloud top heights than the tropopause height below the level of maximum stability. Only the heaviest precipitating clouds vertically extend above this most unstable level.

Uncertainty estimation for Global Navigation Satellite System (GNSS) radio occultation (RO) soundings in the planetary boundary layer (PBL) depends on the algorithms used to process the RO data. We compare the refractivity retrievals from three RO processing centers – each with their own retrieval algorithm – in the PBL, finding a strong underestimation of refractivity in regions with the strongest refractivity gradients, especially in Jet Propulsion Laboratory (JPL) processing, as well as areas of weak overestimation of refractivity near the poles.

Short summary
The EarthCARE/CPR provides the first spaceborne Doppler velocity measurements, while the GPM/DPR excels at observing rain and heavy snow, which are more attenuated in CPR. Using coincident observations from both radars, we examined vertical motions in stratiform and convective precipitation systems. The synergy between the radars enables a more comprehensive understanding of hydrometeor fall speeds and vertical air motions across different precipitation types.

This study explores how different assumptions in cloud microphysics affect the vertical distribution of hydrometeors during extreme precipitation events, such as atmospheric rivers. Using a combination of high-resolution weather simulations and radiative transfer modeling, we identify snow as the dominant contributor to the observed vertical signal. The analysis highlights the sensitivity of precipitation structure to particle properties, that could help refine atmospheric modeling approaches.

This study used Polarimetric radio occultation (PRO) observations to evaluate simulations of cloud hydrometeors with five microphysics schemes for three typhoons from 2019 and 2021. The simulated cloud hydrometeors distributions varied significantly depending on model initial conditions, typhoon structures, and microphysics schemes. Results in this study demonstrate the potential for using PRO observation to evaluate the performance of different microphysics schemes in numerical models.

This dataset provides, for the first time, combined observations of clouds and precipitation with coincident retrievals of atmospheric thermodynamics obtained from the same space-based instrument. Furthermore, it provides the locations of the ray trajectories of the observations along various precipitation-related products interpolated into them with the aim of fostering the use of such dataset in scientific and operational applications.

Short summary
In this article, we described a joint retrieval approach combining two techniques, RO and MWR, to obtain high vertical resolution and solve for temperature and moisture independently. The results show that the complicated structure in the lower troposphere can be better resolved with much smaller biases, and the RO+MWR combination is the most stable scenario in our sensitivity analysis. This approach is also applied to real data (COSMIC-2/Suomi-NPP) to show the promise of joint RO+MWR retrieval.

Short summary
The results of comparing the polarimetric radio occultation observables and the ice water content retrieved from the CloudSat radar in a global and statistical way show a strong correlation between the geographical patterns of both quantities for a wide range of heights. This implies that horizontally oriented hydrometeors are systematically present through the whole globe and through all vertical levels, which could provide insights on the physical processes leading to precipitation.

This study characterizes long-range transport from major Asian pollution sources into the tropical northwest Pacific and the impact of scavenging on these air masses. We combined aircraft observations, HYSPLIT trajectories, reanalysis, and satellite retrievals to reveal distinct composition and size distribution profiles associated with specific emission sources and wet scavenging. The results of this work have implications for international policymaking related to climate and health.

Short summary
Polarimetric radio occultations (PROs) use polarized radio signals from satellites to detect moisture and precipitation in Earth's atmosphere. By applying nonlinear regression and k-means cluster analysis to over 2 years of PRO and non-PRO data, this study shows how deviations from a refractivity model relate to vertical profiles of water vapor pressure (moisture) and that differences between components of PRO signals correlate directly with vertical profiles of water path (precipitation).
