The variations of atmospheric compositions (ACs) can change the interactions with other parts ecosystem, and it also affects energy budget Earth. Satellite remote sensing plays a crucial role in monitoring AC by providing matchless global perspective consistency over long periods. Although China started space exploration missions early 1970s, situation lacking operational satellite was turned around until launch FY-3A 2008. In following decade, more Chinese pathfinder were putting into...
Carbon storage is an important component of ecosystem services. Under climate warming and human activities, land use/land cover (LULC) have been undergoing tremendous change, leading to spatio-temporal variations in carbon storage. Based on seven series LULC data combined with module Integrated Valuation Ecosystem Services Tradeoffs (InVEST) model, spatial-temporal changes types were analyzed estimated for Heilongjiang Province, Northeast China. Results show varied among different LULC....
Understanding the changes in soil enzyme activities and influencing factors after forest fire distur-bances can help assess predict impacts of climate warming on permafrost ecosystems. We analyzed acti-vities extracellular enzyme, including urease (UR), acid phosphatase (AP), acetyl-glucosidase (NAG), β-glucosidase (βG), leucine aminopeptidase (LAP), soils (0-60 cm depth) across unburned, lightly burned severely sites within 2015 area northern Da Xing'anling Monntains. The results showed...
Abstract Transparent 4 at.% Tm:Y 3 ScAl O 12 (Tm:YSAG) laser ceramics were fabricated by solid‐state reaction combined with vacuum sintering method. The Tm:YSAG ceramic sample sintered at 1800°C for 30 hours possesses homogenous microstructure and excellent optical properties, showing a transmittance of 79.3% 2000 nm. absorption emission spectra the are studied compared those Al 5 ceramics. introduction Sc 3+ greatly affects energy levels Tm , causing disappearance degeneration some peaks in...
AIUS (Atmospheric Infrared Ultraspectral Sounder) is an infrared occultation spectrometer onboard the Chinese GaoFen-5 satellite, which covers a spectral range of 2.4–13.3 μm (750–4100 cm−1) with resolution about 0.02 cm−1. was designed to measure and study chemical processes ozone (O3) other trace gases in upper troposphere stratosphere over Antarctic. In this study, retrieval methodology described. A comparison between measurements simulated spectra illustrates that agree well spectra. To...
Urbanization has changed the pattern of urban landscapes and natural landscape. Evaluations spatial temporal changes landscape could support expansion analysis commendably. This study two objectives: (1) to present methods characterize behavioral features corridor effect by using geographical information system (GIS) remote sensing (RS) images (2) apply Lanzhou as an example. In this study, ERDAS IMAGINE was used process prepare RS digital land-use maps. addition, on extracted man-machine...
The Atmospheric Infrared Ultraspectral Sounder (AIUS), the first high-resolution (0.02 cm−1) solar occultation sounder, aboard GF5, was launched in May 2018 from China. However, relevant studies about vertical profiles of atmospheric constituents based on its operational data were not conducted until half a year later. Due to an urgent need for Hin-orbit tests, real spectra (called reference hereafter) substituted with simulated calculated forward model (RFM) plus different random noises at...
Pointing information is decisive to solving precise profile retrieval issues from occultation measurements. Research regarding stratospheric O3 hole in Antarctic and surface pollution would significantly benefit massive A neural network aided pointing determination approach, terms of tangent heights, proposed address requiring fast easy-to-use determined heights. The geometrical triangular iteration (GTI) algorithm this work based on N2 absorption microwindows, several treatments (e.g.,...
To assess the genetic background of germplasm resource rainbow clam Moerella iridescens along China coasts, population structure and diversity from five geographical populations in Yellow Sea East (Lianyungang, Chongming, Cixi, Zhoushan, Ningde) were analyzed based on rDNA (ITS1-5.8S-ITS2) sequences. Forty-Seven haplotypes identified among 109 individuals populations. Gen4 Gen21 dominant haplotypes, accounting for 49.5% whole gene sequences, shared by Six to eight exclusive found each...
Recently, the frequent seasonal drought in Southwest China has brought considerable concerns and continuous heated arguments on “water pump” viewpoint (i.e., water demand from Hevea spp. Eucalyptus can be treated as a pump) once again. However, such just focused consumption vegetation transpiration its ecoenvironment impacts, which had not considered other attributes of vegetation, namely, saving resistance, hydrological regulation (water conservation) into consideration. Thus, this paper,...

Infrared imaging can detect the targets from their backgrounds during day and night. As a supplementary tool, polarization visually characterize polarized information of in complicated environments. In this study, an infrared system with local channel is developed simulated. The acquire target without compromising monitoring entire field view. This composed two channels common image plane: peripheral for view interest to achieve magnification imaging. Herein, simulation performed, results...
TERRA MODIS band 31 was selected as the criterion for doing radiometric cross-calibration of CBERS-02 IRMSS 9 in this paper. From August to December, 2004, seven times day and night synchronous images two sensors passing through Lake Qinghai Taihu were get data. Using data conduct out at pupil radiance based on sensors' spectrum matching, then pick-up DN values from same area. A new model calculate calibration coefficients carried paper: multi-points linear regression method with 7 different...
Atmospheric Infrared Ultraspectral Sounder (AIUS) aboard the Chinese GaoFen-5 satellite was launched on 9 May 2018. It is first hyperspectral occultation spectrometer in China. The spectral quality assessment of AIUS measurements at full and representative bands presented by comparing transmittance spectra with that simulations. agree well Statistics show more than 73% differences are within ±0.05 91% ±0.1. windows for O3, H2O, temperature, CO, CH4, HCl were also analyzed. comparison...
