Surface Solar Irradiance (SSI) is a key parameter dictating surface-atmosphere interactions, driving radiative, hydrological, and land surface processes, can thus impinge greatly upon weather climate. It thereby prerequisite of many studies applications. Estimating SSI from satellites began in the 1960s, currently principal way to map spatiotemporal distributions regional global scales. Starting an overview historical carried out past several decades, this paper reviews progresses made...
As a new type of two-dimensional crystal material, black phosphorus (BP) exhibits excellent electronics and optical performance. Herein, we focus on carrier relaxation dynamics nonlinear properties BP suspension. Atomic force microscopy, transmission electron spectrum are employed to characterize the structure linear BP. Additionally, pump-probe experiments at wavelength 1550 nm were carried out study in suspension, ultrafast recovery time was observed (τs = 24 ± 2 fs). Furthermore,...
Abstract. A long-term Advanced Very High Resolution Radiometer (AVHRR) snow cover extent (SCE) product from 1981 until 2019 over China has been generated by the research team in Northwest Institute of Eco-Environment and Resources (NIEER), Chinese Academy Sciences. The NIEER AVHRR SCE a spatial resolution 5 km daily temporal resolution, it is completely gap-free product, which produced through series processes such as quality control, cloud detection, discrimination, gap-filling (GF)....
Abstract. Based on MOD09GA/MYD09GA surface reflectance data, a new MODIS snow-cover-extent (SCE) product from 2000 to 2020 over China has been produced by the Northwest Institute of Eco-Environment and Resources (NIEER), Chinese Academy Sciences. The NIEER SCE contains two preliminary clear-sky datasets – Terra-MODIS Aqua-MODIS final daily cloud-gap-filled (CGF) dataset. first are generated mainly through optimizing snow-cover discriminating rules land-cover types, latter dataset is after...
[1] In this paper, a new satellite-derived approach for obtaining instantaneous surface solar irradiance (SSI) by combining Moderate Resolution Imaging Spectroradiometer (MODIS) and Multifunctional Transport Satellite (MTSAT) data is presented validated using one year pyranometer measurements from five stations in northern China. The based on look-up tables created via comprehensive radiative transfer modeling to achieve high accuracy computational efficiency. synergy of the multispectral...
Abstract Gross primary production (GPP) is an important variable in studies of the carbon cycle and climate change. The Moderate Resolution Imaging Spectroradiometer (MODIS)-GPP product (MOD17) provides global GPP data for terrestrial ecosystems; however, it not well validated China. In this study, eddy covariance (EC) system observed at 10 sites northern China was used to validate MOD17. results indicated that MOD17 presents a strong bias study region due meteorological data, MODIS FPAR...
We consider the resolution of single-frequency reverse time migration method for extended targets without assumption validation geometric optics approximation. The analysis, which applies in both penetrable and non-penetrable obstacles with sound soft or impedance boundary condition on obstacle, implies that imaginary part cross-correlation imaging functional is always positive thus may have better stability properties. Numerical experiments are included to illustrate powerful quality...
Comparing with observations, the abnormally smaller cloud absorption (to solar radiation) given by climate models (namely alleged anomaly) ever raised widespread concerns in mid-1990s and early 2000s but was seldom mentioned thereafter. Based on three state-of-the-art modeled products, NCEP CFSv2, ECMWF ERA5 NASA MERRA2, newest collocated satellite-surface observation last 12 years (2012–2023), we reinvestigate this controversial issue. Our results demonstrate observed of radiation...
Photosynthetically active radiation (PAR) incident at the surface is crucial for understanding and modeling Earth's climate ecosystems. In this article, a general parameterization scheme suitable PAR estimation under cloudy skies proposed based on an elaboration radiative transfer (RT) processes above, in, beneath cloud layers. Its most important novel property that all RT in atmospheres are explicitly explained, including ozone absorption, Rayleigh scattering, single multiple aerosol...
Net surface shortwave radiation (NSSR) is a key quantity for the estimation of energy budget and used in various land-surface models. In this article, two different methodologies, including three empirical algorithms one advanced simplified theoretical algorithm estimating instantaneous NSSR from Moderate Resolution Imaging Spectroradiometer (MODIS) data are explored summarized. An developed by combining radiative-transfer models with MODIS atmosphere land products. To comprehensively...
Abstract A broadband parameterization scheme for estimating surface solar irradiance (SSI, ~ 0.3–4.0 μm) is developed based on extensive radiative transfer simulations a diversity of atmospheric conditions. In the new scheme, accumulated SSI arriving at considered as whole, but different attenuations, such ozone absorption, permanent gas water vapor Rayleigh scattering, aerosol absorption and cloud are accounted separately. particular, single scattering multiple clouds parameterized...
Aerosol Optical Depth (AOD) is one of the most important optical properties aerosols that may affect energy budgets our Earth–atmosphere system significantly. Currently, while regional and even global AOD knowledge has been given by various satellites or models, these products are still fraught with uncertainties. In this study, sophisticated satellite-derived product from MODIS (MODerate resolution Imaging Spectral-radiometer) two state-of-the-art model-based CAMS (Copernicus Atmosphere...
The sensitivity of synthetic aperture radar (SAR) polarization information to snow depth changes provides new opportunities for regional retrieval in mountains with thick cover. However, interference from soil signals can affect the accurate quantification volume scattering signals. aim this study was develop a dual-polarimetric estimation (DpRSE) methodological framework that utilizes Sentinel-1 data Scandinavian Mountains. This is based on vegetation index (DpRVIc), which enhances signal...
Snow depth (SD) is an indispensable parameter for many studies. Launched in 2018, the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) designed to obtain global glacial elevations, but it can also acquire canopy terrain elevations. Whether of seasonal snow be estimated by directly comparing difference elevations snow-cover snow-free cases, people may reasonably ask. In this letter, we conduct such investigation Altay, Northwest China, using ICESat-2 ATL08 elevation products. Our...
