Abstract. The dust aerosol radiative forcing and heating rate over the Taklimakan Desert in Northwestern China July 2006 are estimated using Fu-Liou transfer model along with satellite observations. vertical distributions of extinction coefficient derived from CALIPSO (Cloud-Aerosol Lidar Infrared Pathfinder Satellite Observations) lidar measurements. CERES (Cloud Earth's Energy Budget Scanner) measurements reflected solar radiation used to constrain type model, which determines...
The Atmosphere Radiation Measurements Program's Ancillary Facility (AAF/SMART‐COMMIT) was deployed to Zhangye (39.082°N, 100.276°E), which is located in a semidesert area of northwest China, during the period late April mid June 2008. We selected 11 cases retrieve dust aerosol optical depth (AOD), Angstrom exponent, size distribution, single‐scattering albedo (SSA) and asymmetry parameter (ASY) from multifilter rotating shadowband radiometer (MFRSR) measurements. These are dominated by large...
Abstract Using field observations, we perform radiative transfer calculations on snowpacks in the Arctic, China, and North America to quantify impact of light‐absorbing particles (LAPs) snow albedo its sensitivity different factors. For new snow, regional‐averaged reductions caused by all LAPs America, China are 0.009, 0.012, 0.077, respectively, which black carbon (BC) alone 0.005, 0.031, corresponding a positive forcing 0.06, 0.3, 3 W m −2 . same particulate concentrations, reduction for...
Zenith tropospheric delay (ZTD) is one of the main error sources in space geodesy. The existing regional or global models, such as Global Pressure and Temperature 3 (GPT3), Tropospheric model, Hopfield, Shanghai Astronomical observatory model have good performance. However, precision these models relatively low regions with a large height difference, which becomes focus this article. A high-precision ZTD considering effect on proposed, China selected study area due to its called for (CHZ)....
Long-term observational data indicated a decreasing trend for the amount of autumn precipitation (i.e. 54.3 mm per decade) over Mid-Eastern China, especially after 1980s (similar to 5.6% decade). To examine cause trend, mechanisms associated with change were investigated from perspective water vapor transportation, atmospheric stability and cloud microphysics. Results show that decrease convective available potential energy 12.81 J kg(-1)/ microphysics, which closely related increase aerosol...
Modeled and observed solar diffuse fluxes at the surface usually have unacceptably large discrepancies. It is necessary to address resolve these discrepancies in order accurately calculate a reliable aerosol direct radiative forcing (DRF). We present compare two methods of deriving dust optical properties from MFRSR (Multi-Filter Rotating Shadowband Radiometer) observations AERONET products. The single-scattering albedo (SSA) values are found be 10% less than those AERONET. This difference...
Zenith Tropospheric Delay (ZTD) is an important factor that restricts the high-precision positioning of global navigation satellite system (GNSS), and it great significance in establishing a real-time ZTD model. However, existing models only consider impact linear terms on estimation, whereas nonlinear factors have rarely been investigated before thus become focus this study. A model for large height difference area proposed by considering characteristics spatiotemporal variations called...
Abstract The change in clouds during the day is critical to Earth's energy balance and climatic evolution. However, there have been relatively few studies on cloud variations at daily timescales, owing limitations of ground‐ satellite‐observations, especially for cirrus clouds. In this study, we examined daytime variation (DCV) global scales its associated effects radiation budgets based International Satellite Cloud Climatology Project H data set. changes continental cover are more...
Abstract Dust and high cloud interactions are critical for climate change, primarily due to the dominant roles of in greenhouse effect continental precipitation. Nonetheless, disentangling specific impacts dust from overlying meteorology influence on clouds presents great challenges. In this study, we construct a meteorological pattern that successfully reveal intricate connection between distribution atmospheric conditions. Through strong bounded relationship, find exhibits notable controls...

Dust events not only cause local ecosystem degradation and desertification, but also have profound impacts on regional global climate system, as well air quality human health. in Xinjiang Basin, the important dust source of Eastern Asia, undergone a significant change under warming background may be new active period after 2000, which is worthy study. This study provides temporal spatial variations Basin based surface meteorological station observation data during 1960–2015. The results show...
As one of the important factors in atmospheric physical and chemical processes, aerosol optical depth (AOD) has an impact on regional global climate. Therefore, monitoring predicting temporal spatial changes AOD is considerable significance. Existing methods mainly use a large number meteorological parameters ground observations to forecast AOD. However, modeling data are numerous difficult obtain practically. In this study, adaptive forecasting (AAF) model proposed using zenith total delay...

Low-level clouds (LLC), mainly composed of liquid water droplets, cool the climate system by strongly reflecting solar radiation back to space, and thus play an important role in Earth energy budget. However, LLC properties their radiative effects are poorly represented models, leading largest source uncertainty prediction. Liquid content (LWC) is a key property determining cloud extinction characteristics fundamental parameter transfer model. To improve understanding LWC properties,...
