Abstract An N‐Dimensional Cost Function (NDCF) method is introduced in this paper to simultaneously retrieve aerosol optical depth (AOD) at multiple time points by exploiting multitemporal data synergy from geostationary satellite. In the proposed method, number of remote sensing observations used flexible, bidirectional reflectance effect considered, and AOD variation different allowed. Sensitivity study shows that relative error retrieved decreases as dimension cost function increases. The...

Abstract. To investigate the impacts of multiscale circulations on planetary boundary layer (PBL), we have carried out PBL thermodynamic structure field experiment with a Doppler wind profile lidar, microwave radiometer, and ceilometer from January 2018 to December 2019 in Beijing. We found that direct regulatory effect synoptic circulation worked through transporting accumulating pollutants front mountains daytime, while indirect coupling mechanisms nighttime. The horizontal...

This paper reveals a study on air pollution process over North China, applying remote sensing technology, using satellite observation and in situ measurements during the twenty-first Asia-Pacific Economic Cooperation (APEC) meeting, which was held Beijing between 6 12 November when clear weather called “APEC-Blue”. In meantime, pollutants concentrations including PM2.5 PM10 were lower than 100 μg/m3 owing to effective government measures policies, as well meteorological conditions. High...

We compared and evaluated the performance of five methods for detecting abrupt climate changes using a time series with artificially generated characteristics. Next, we analyzed these annual mean surface air temperature records from Shenyang meteorological station.

This paper presents a unified model for image editing in terms of Sparse Matrix-Vector (SpMV) multiplication. In our framework, we cast as linear energy minimization problem and address it by solving sparse system, which is able to yield globally optimal solution. First, three classical operations, including filtering, resizing selecting, are reformulated the SpMV multiplication form. The form helps us set up straightforward mechanism flexibly naturally combine various features (low-level...

Data compression has been proposed to increase the utility of on-chip memory space or Network-on-Chip (NoC) bandwidth in energy-efficient processors. However, such techniques usually add additional and decompression latency critical path access, which is one major factors limiting their application In contrast prior work that deals with either cache network separately, this study proposes a unified DIStributed data COmpressor, DISCO, enable near-zero cache/NoC for chip multi-processors...
