This paper presents an evaluation of the quality data from MicroWave Humidity Sounder-2, flown on FY-3C polar orbiting satellite, and first results trials assimilating in all-sky conditions European Centre for Medium Range Weather Forecasts' assimilation system. instrument combines traditional microwave humidity sounding capabilities at 183 GHz with new channels 118 GHz, which have never before been available space. The aim this is twofold: to contribute calibration/validation satellite by...
Precipitation is the basic component of Earth’s water cycle. Obtaining high-resolution and high-precision precipitation data great significance. This paper establishes a retrieval model based on random forest classification regression during day at night with FY-4B/AGRI Level1 China from July to August 2022. To evaluate effect model, GPM IMERG product used as reference, results are compared against those operational product. In addition, analyzed according different underlying surfaces. The...
On 12 May 2008 the magnitude 8.0 Wenchuan Earthquake erupted on eastern fringe of Tibetan Plateau in China, triggering many landslides onto towns and villages, leading to substantial loss life damage property infrastructure. Local characteristic cloudy weather posed serious difficulties upon regional remote observation for disaster rescue mountainous region. To overcome limits sensing, study advanced one quick methodology extract primary with 8-day Moderate Resolution Imaging...
This study proposes a new technique for retrieving temperature and humidity profiles based on Artificial Neural Networks (ANNs) using data acquired from the GIIRS (Geosynchronous Interferometric Infrared Sounder) L1 ERA-Interim (European Centre Medium-Range Weather Forecasts Reanalysis). The approach is also compared against another method that uses simulated radiative transfer model to construct retrieval network. Furthermore, two methods of network construction are evaluated in North China...
The polar-orbiting meteorological satellites operating in an observing system composed of early morning (EM), midmorning (AM), and afternoon (PM) orbits are extremely important to global numerical weather prediction (NWP). Following the proposal World Meteorological Organization (WMO), China Administration (CMA) launched Fengyun-3E (FY-3E), world's first EM-orbit satellite for civil use, on 5 July 2021. With 11 scientific instruments board, FY-3E is capable providing atmospheric sounding,...
Abstract China’s Feng-Yun-3A (FY-3A), launched in May 2008, is the first a series of seven polar-orbiting meteorological satellites planned for next decade by China. The FY-3 set to become an important data source numerical weather prediction (NWP), reanalysis, and climate science. FY-3A equipped with microwave temperature sounding instrument (MWTS). This study reports assessment MWTS using ECMWF NWP model, radiative transfer modeling, comparisons equivalent observations from Advanced...
Abstract This paper evaluates the microwave instruments onboard latest Chinese polar-orbiting satellite, Feng-Yun 3D (FY-3D). Comparing three months of observations from Microwave Temperature Sounder 2 (MWTS-2), Humidity (MWHS-2), and Radiation Imager (MWRI) to Met Office short-range forecasts, we characterize instrumental biases, show how those biases have changed with respect their predecessors FY-3C, they compare Advanced Technology (ATMS) NOAA-20 Global Precipitation Measurement (GMI)....
<title>Abstract</title> Using precipitation data from the Mount Emei station, along with CRU and APHRODITE datasets various reanalysis products, we examined interdecadal change in relationship between summer on southeastern edge of Tibetan Plateau (SETP) tropical sea surface temperature (SST). Our findings indicate that negative correlation SETP rainfall SST central-eastern Pacific significantly enhanced 1985 to 2005 (P2) compared earlier period 1958 1978 (P1). An anomalous anticyclone belt...
Abstract FY‐3A, launched in May 2008, is the first a series of seven polar‐orbiting meteorological satellites due to be by China's Meteorological Administration period leading up 2020. The FY‐3A payload includes four instruments particular interest for numerical weather prediction (NWP): microwave temperature and humidity sounders, imager, an infrared sounder. main features these are described. Data from calibration–validation phase mission were introduced into ECMWF Integrated Forecasting...
Highly charged ions (HCIs) are promising candidates for the next generation of atomic clocks, owing to their tightly bound electron cloud, which significantly suppresses common environmental disturbances quantum oscillator. Here we propose and pursue an experimental strategy that, while focusing on various HCIs a single element, keeps number candidate clock transitions as large possible. Following this strategy, identify four adjacent charge states nickel that offer many six optical...
HIRAS-II is the hyperspectral detector carried on FengYun-3E which world’s first meteorological satellite in dawn–dusk orbit. It fills observation gaps during dawn and dusk periods of polar orbit satellites, enabling a 100% global data coverage assimilation within each 6 h window for numerical weather forecasting models. With 3053 vertical detection channels, it provides high-resolution temperature humidity information, thus playing an important role improving forecast skills medium-range...

Fengyun (FY) satellite program is becoming the important component of global earth observing system. Its instrumental performance, i.e., data quality and stability, play a critical role to support quantitative applications, such as atmospheric surface parameter retrievals, numerical weather prediction (NWP) production Climate Data Records (CDRs). For monitoring radiative transfer models (RTMs) together with NWP fields are used simulate reference radiance in FY instrument schemes (FY-SIMS)....
Near-infrared (NIR) channels, such as the 1.6- and 2.13-μm channels of Moderate Resolution Imaging Spectroradiometer (MODIS), play an important role in inferring cloud properties because their sensitivity to amount particle size.
