Agriculture plays important role in economic and social development in China. Diverse climatic and geomorphological conditions make it difficult to monitor agriculture timely and accurately in China. In this paper, we demonstrated the application of GF-1 imager and data products in agricultural monitoring in China.
A novel algorithm is developed for the automatic detecting the center of tropical cyclones (TC) using the infrared (IR) images from geostationary satellites. Edge detection and density matrix are utilized to determine the center of TC. FY-2F IR images of two TC, Usagi (September 17–23, 2013) and Haiyan (November 3–12, 2013) have been analyzed using the proposed algorithm. Experimental results compared...
Quantitative retrieval is a growing area in remote sensing due to the rapid development of remote instruments and retrieval algorithms. The aerosol optical depth (AOD) is a significant optical property of aerosol which is involved in further applications such as the atmospheric correction of remotely sensed surface features, monitoring of volcanic eruptions or forest fires, air quality, and even climate...
Image classifications including sub pixel analysis are often used to estimate directly the crop acreage, while ground data collected during field surveys play a secondary role. This type of crop area assessment using image classifications often leads to a biased estimation due to non-representative selection of training data and subjective a-priori knowledge. Instead regression estimator approach...
A new algorithm for Land Aerosol property and Bidirectional reflectance Inversion by Time Series technique (LABITS) is presented and applied to National Oceanic and Atmospheric Administration Advanced Very High Resolution Radiometer (NOAA AVHRR) data over China. Based on the assumptions that the surface bidirectional reflective property are not varying during one day and aerosol characteristics are...
Data assimilation is important to the improvement of numerical weather prediction (NWP). Recently, much progress has been made in the direct assimilation of satellite radiance in NWP. In order to use radiance from the infrared channels of the visible and infrared radiometer (VIRR) on FY-3A, biases between the observed radiances and those simulated from model must be corrected. Using the radiosonde...
It is important for the improvement of numerical weather forecast accuracy to reseach the simulation error of rapid radiative transfer model. Using the radiosonde data as the input of rapid radiant transfer model CRTM, the simulation error of infrared channels observation of VIRR on FY-3A is analyzed. The distribution of model biases in radiance of three infrared channels are approximate normal ditribution,...
This paper has focused on a new automated detection and removal of cloud shadows of remotely sensed data to service quantitative interval of atmospheric parameters, using the FengYun-3 (FY-3), moderate spatial resolution and HuanJing-1 (HJ-1), high spatial resolution satellite data. Taking into account interaction between neighboring pixels in remote sensing images, this research aims at the special...
The thermal control of developing nano-satellite will be challenging due to the continually rising tendency of the power densities on board and the complicatedly ever-changing orbital thermal environment. The paper is aimed at modeling and analysis of an active thermal control system for on-orbit nano-satellite used MEMS (Micro Electro Mechanical Systems)-based pumped liquid micro channel efficient...
