Land-Atmosphere Interactions and Land Surface Temperature Distribution in Central Yunnan

1. Introduction Land surface temperature (LST) is an important factor for the regional and world(prenominal) scales of physical, chemical and biological processes on mankind. The average surface temperature of hide is 288K. The LST is affected by land surface-atmosphere interactions and energy fluxes among the shine and the ground. Therefore, it is a good indicator of the energy balance between farming surface and atmosphere as well as the nursery effect. The traditional method of monitoring surface temperature is hard-fought to richly rally the temperature entropy, while the high up-resolution remote spotting applied science renders an effective mean of comprehensive monitoring for a across-the-board revolve of surface temperature, the accuracy of which can be up to 1K. Therefore in this project, we use the MODIS data to retrieve the LST by split-window algorithm. The study land orbital cavity is primaeval Yunnan. We provide display the retrieval result of LST in this paper. Based on the retrieving result we will also analyze the LST distribution of the obscure Yunnan res publica and discuss the factors that affect regional LST and the land-atmosphere energy fluxes. 2. lie with Area Yunnan Province is situated in a hilly area, with high elevations in the northwest and low elevations in the southeast. The underlying Yunnan area is locate between 100°0 27.11 to 103°4 20.

41E and 22° 09 55.19 to 27° 00 24.71N. It consists of central and eastern part of Yunnan, which is the principal(prenominal) part of the Yunnan Plateau. Central Yunnan plateau has an average elevation of roughly 2000 meters, and the vegetation is ! in general subtropical evergreen broad-leafed woodland. The red line do area in next picture shows the Central Yunnan area we study on. ?3. Methodology 3.1. selective information Source FIGURE 1 CENTRAL YUNNAN AREA In this study, we retrieve the LST based on data from MODIS. The original MODIS data is from the Goddard Space Flight Center of NASA1, and the data is obtained in descent 2009. MODIS has 36 bands including five...If you want to get a full essay, range it on our website: OrderCustomPaper.com
