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 basis 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 kingdom surface and atmosphere as well as the nursery effect. The traditional method of monitoring surface temperature is hard-fought to to the full rally the temperature entropy, while the high up-resolution remote spotting engineering set ups an effective mean of comprehensive monitoring for a childlike take to the woods of surface temperature, the accuracy of which can be up to 1K. Therefore in this project, we use the MODIS selective information to retrieve the LST by split-window algorithm. The study land orbital cavity is primaeval Yunnan. We provide display the retr ieval result of LST in this paper. Based on the retrieving result we will also analyze the LST distribution of the difficult Yunnan res publica and discuss the factors that affect regional LST and the land-atmosphere energy fluxes. 2. figure Area Yunnan Province is situated in a unsmooth area, with high elevations in the northwest and low elevations in the southeast. The rudimentary 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 of import part of the Yunnan Plateau. Central Yunnan plateau has an a verage elevation of nigh 2000 meters, and t! he vegetation is in general subtropical evergreen deciduous woodland. The red line do area in followers picture shows the Central Yunnan area we study on. ?3. Methodology 3.1. entropy 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 stemma 2009. MODIS has 36 bands including five...If you want to get a full essay, range it on our website: BestEssayCheap.com
