Climate variability in urban cities of Tegucigalpa and Comayagüela, Francisco Morazan, Honduras in the period between 1975 - 2011

Abstract

In this paper we study the climatic variability in Honduras Central District which includes the capital Tegucigalpa and Comayagüela as neighboring city, temporary space analysis covers the dates 1975, 1987, 2000 and 2011. In the first stage examines urban growth pattern which shows that there have been several changes in the first years of study, this stage of analysis if produced by sensor Landsat satellite images, these images will be calculating the vegetation index (NDVI) which separates the plant areas devoid of vegetation which makes us an excerpt from urban and thus remove them more easily, then evaluated the results of the analysis of Landsat satellite band 6 which corresponds to the thermal band with which we can draw soil temperature at the time the image was taken, it is important to mention that the images correspond to the first quarter of the year and in this analysis do not have the year 1975 because the sensor was not installed that capacity at the time; joined these analyzes was analyzed certain atmospheric monitoring stations and worked through geostatistics which throw a figure not so local as the stations were too far apart to shed a little more specific analysis. The sum of all these variables is the main contribution of this study to guide studies somehow the topic of climatic variability and urban growth.
