Abstract Warm rain prevails in clean marine clouds and is one of the most abundant types precipitation world. However, warm rarely observed urban polluted atmospheric environments due to high number concentrations aerosols generally suppress occurrence rain. Three aircraft observation were used during summer Beijing area. Here, we documented processes similar shallow (Beijing) environment after cleansing air pollution by extensive on 11 September 2019. Our results showed that, compared with...
Retrieving cloud vertical structures with satellite remote-sensing measurements is highly desirable and technically challenging. In this paper, the conditional adversarial neural network (CGAN) for retrieving equivalent radar reflectivity at 94 GHz of Cloud Profile Radar (CPR) onboard CloudSat extended evaluated comprehensively different types geographical regions. The CGAN-based retrieval model was additional data samples improved a new normalization adjustment. trained labeled datasets...
This study extends the CGAN-based MODIS cloud vertical-profile (64×64-scene, about 70km width×15km height) retrieval technique developed by Leinonen et al. (2019) [1] to construct seamless 3D fields for granules [2]. Firstly, accuracy and spatial continuity of retrievals are statistically evaluated. Then, according characteristics error, a spatially overlapping-scene ensemble generation method bi-directional Ensemble Binning Probability Fusion (CGAN-BEBPF) developed, which improves CGAN...
Abstract The surface of atmospheric aqueous aerosol is covered with an organic film. However, there have been limited studies about the photochemical process between coating and samples such as fogwater, which contains light absorbing brown carbon (BrC). Here, interactional aging unsaturated fatty acids was performed by laboratory field observations. On one hand, glycine alanine were selected nitrogen‐containing compounds to form BrC carbonyl like glyoxal or methylglyoxal. Oleic acid induced...
Biological particles, as a fraction of organic potentially play crucial role in ice nucleation processes. However, the contributions and relationships biological components matter (OM) to atmospheric are still largely unexplored. Here, droplet freezing assays, high-throughput sequencing technology ultrahigh-resolution mass spectrometry were performed detect INPs, microorganisms OM molecules precipitation collected at summit Mt. Lu, China, respectively. Results revealed predominant...
Accurate three-dimensional (3D) cloud structure measurements are critical for assessing the influence of clouds on Earth’s atmospheric system. This study extended MODIS (Moderate-Resolution Imaging Spectroradiometer) vertical profile (64 × 64 scene, about 70 km in width 15 height) retrieval technique based conditional generative adversarial networks (CGAN) to construct seamless 3D fields granules. Firstly, accuracy and spatial continuity retrievals (of 7180 samples from validation set) were...
Abstract Biological particles, as a fraction of organic potentially play crucial role in ice nucleation processes. However, the contributions and relationships biological components matter (OM) to atmospheric remain largely unexplored. Here, total nucleating particles (INPs), heat‐resistant INPs, lysozyme‐resistant nanoscale INPs (<0.22 μm), precipitation collected at summit Mt. Lu, China, were determined using droplet freezing assays coupled with corresponding pretreatments....
Lidar is the primary tool used to determine vertical distribution of aerosol optical characteristics. Based on observation characteristics mountain’s gradient, a validation analysis remote sensing and in situ observations research seasonal, monthly, daily variations depth (AOD) were performed using dual-wavelength deployed at foot Mt. Lu particle-size spectrometer top Lu. The results show that comparison heights, under cloudy-sky conditions with strong winds (>3.4 m/s) high relative...
Abstract This study proposes a method for direct assimilation of radar reflectivity in cycled deterministic forecast systems using time‐lagged ensemble based Kalman filter with the “cloud‐dependent” background error covariances. With this method, forecasts from multiple cycles that are initialized at different times but valid same time, collected as to compute An algorithm specified covariances was devised, which vertical covariance is computed each “cloud‐feature” bins divided according...
The study of the characteristics and variations cloud condensation nuclei (CCN) plays an important role in understanding effects aerosol–cloud interactions. This paper selected observation data a city region Shijiazhuang North China from 2005 to 2007, along with corresponding MERRA-2 ERA5 data, analyze CCN, sort factors affecting diurnal variation CCN number concentration (NCCN) according their importance, build relationship between NCCN supersaturation (SS) heavily polluted region. results...
&lt;p&gt;Using in-situ aircraft observations from six flights over Zhejiang on Sep. 1 and 4, 2016, this study investigates differences in aerosol cloud properties between daytime nighttime. The samples were divided into marine type continental based the backward air mass trajectories characteristics. results show that number concentration (N&lt;sub&gt;a&lt;/sub&gt;) near ground during is higher than at During daytime, Na has a significant decreasing trend top of...
