Abstract This paper introduces the Flexible Global Ocean‐Atmosphere‐Land System Model: Grid‐Point Version 3 (FGOALS‐g3) and evaluates its basic performance based on some of participation in sixth phase Coupled Model Intercomparison Project (CMIP6) experiments. Our results show that many significant improvements have been achieved by FGOALS‐g3 terms climatological mean states, variabilities, long‐term trends. For example, has a small (−0.015°C/100 yr) climate drift 700‐yr preindustrial...
Abstract. Physical parameterizations in general circulation models (GCMs), having various uncertain parameters, greatly impact model performance and climate sensitivity. Traditional manual empirical tuning of these parameters is time-consuming ineffective. In this study, a "three-step" methodology proposed to automatically effectively obtain the optimum combination some key cloud convective according comprehensive objective evaluation metrics. Different from traditional optimization methods,...
The Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) was launched on September 15, 2018. It is the first photon-counting laser altimeter satellite, which of great significance for research into altimetry. ICESat-2 is, however, highly sensitive susceptible to environmental influences. In addition surface returns, a lot nonsurface photons are found in data. therefore, necessary study an effective method separate signal from background information. this article, we review existing...
Abstract Reducing the double Intertropical Convergence Zone (ITCZ) bias has long been subject of intensive research among climate modeling community; however, role uncertain moist physical parameters from atmospheric component model in causing ITCZ not analyzed systematically. This study investigated potential for reducing through perturbing nine parameters, using uniform sampling and Latin hypercube methods, quantified parametric uncertainty effects two‐way interactions overall nonlinear...
It is challenging to use traditional remote sensing techniques accurately determine the extent and thickness of ice in Bohai Sea, on account presence sea impurities (i.e. mud, salt bubbles sand) shape irregularities. Accordingly, we performed a series reflectance spectra experiments empirically link measurements surface with situ Sea. Two years Thematic Mapper (TM) band 2 Moderate Resolution Imaging Spectroradiometer (MODIS) 4 data were used distinguish between following types, using...
Abstract The Grid‐point Atmospheric Model of the IAP LASG version 3 (GAMIL3) has been developed by upgrading horizontal resolution, methods parallel computation, boundary layer scheme, aerosol parameterization, convective stratocumulus cloud fraction land component, and coupler, as well tuning some moist physical parameters with large uncertainties. Its performance is evaluated, results show significant improvements compared previous version, GAMIL2. simulated mean states notably enhanced,...
Researchers have studied oil spills in open waters using remote sensors, but few focused on extracting reflectance features of pollution sea ice. An experiment was conducted natural ice Bohai Bay, China, to obtain the spectral oil-contaminated The absorption index (SAI), peak height (SPH), and wavelet detail coefficient (DWT d5) were calculated stepwise multiple linear regression. reflectances some false targets measured analysed. simulated sediment, iron ore fines, coal dust, melt pool....
The Hengduan Mountains Region (HMR) is the largest "evolutionary frontier" of northern temperate zone, and origin maintenance species in this area a research hotspot. Exploring species-specific responses to historical contemporary environmental changes will improve our understanding role region maintaining biodiversity. In study, mitochondrial microsatellite diversities were used assess contributions paleogeological events, Pleistocene climatic oscillations, landscape characteristics rapid...
Sample series of clean regular‐shaped ice representative thermal interaction processes only were gathered in a controlled experiment on floes China's Bohai Sea. Based these samples, spectral characteristics for one‐year‐old sea measured and analyzed. The same experiments then performed samples with two normal impurities the results compared against those samples. Along increasing thickness, reflectance rises form ladder within visible light range. While flat is covered by thaws snow and/or...
The thicknesses of level and rough sea ice in the Bohai Sea were estimated, using Huan Jing-1 (HJ-1) charge-coupled device (CCD) images environmental satellite (ENVISAT) advanced synthetic aperture radar (ASAR) images, respectively. Two empirical models developed, one to describe relationship between reflectance visible/near-infrared (VIS/NIR) imagery thickness backscattering coefficient (SAR) thickness. results showed that VIS/NIR more suitable for distinguishing from water, active...
Normalized Moran's I index is an indispensable component in maintaining multi-species distributional aggregation at local scales.
The emergence of hyperspectral thermal infrared imaging spectrometers makes it possible to retrieve both the land surface temperature (LST) and emissivity (LSE) simultaneously. However, few articles focus on problem how instrument's spectral parameters instrument noise level affect LST LSE inversion errors. In terms development, this article simulated three groups data with common each group includes tens millions radiances 1525 curves 17 center wavelength shift ratios, 6 full width at half...

Confused geographical structure of a population and mitonuclear discordance are shaped by combination rapid changes in demographics shifts ecology. In this study, we generated time-calibrated phylogeny Scutigerboulengeri, an endemic Xizang alpine toad occurring mountain streams on the Qinghai-Xizang (Tibet) Plateau (QTP). Based three mitochondrial DNA (mtDNA) genes, eight clades were assigned to deeply divergent lineages. Analysis nuclear (nuDNA) genes revealed distinct clusters without...
There are numerous algorithms that can be used to retrieve land surface temperature (LST) and emissivity (LSE) from hyperspectral thermal infrared (HTIR) data. The sensitive a number of factors, where noise is difficult handle due its unpredictability. Although there lot research regarding the influence on retrieval errors, few studies have focused mechanism. In this study, we selected automatic using spectral smoothness (ARTEMISS) algorithm—the representative iterative...
