A visual comparison of climate and vegetation on a global scale immediately reveals a strong association between climate and vegetation. The main object of this study is to reveal the spatiotemporal association between climatic factors and Modis derived NDVI in Charmahal&Bakhtiary province of Iran.Material and Methods: In this study, we use MOD13A3 of MODIS product as NDVI layer for study area. MOD11A2 as land surface temperature and mean monthly accumulative rainfall of synoptic station for study area during 2008 to 2018. We used the correlation analysis in 0.95 confident level (P_value =0.5) to reveal the spatiotemporal association between the NDVI and climatic factors.Results: The results indicated that during winter (December to March) the spatial distribution of NDVI is highly correlated with LST spatial distribution. In these months, the pixels which have the high value of NDVI are spatially associated with the pixels which have highest value of LST (6 to 12C°). In winter the spatial correlation between NDVI and LST is so high which is statistical significant in 0.95 confident level. In transient months such as May, October and November, the spatial correlation between NDVI and LST is falling to 0.30 to 0.35, which is not statistical, significant in 0.95 confident level. Finally, in summer season or warm months including Jun to September, we found the minimum spatial association between the NDVI and LST.Conclusion: we found that the maximum correlation between NDVI and LST simultaneously appears and no lag time has been observed. The spatial correlation of NDVI and monthly accumulative rainfall was statistical significant in spring season (April to Jun) by 1 month lag time but in other months we do not find any significant correlation between NDVI and rainfall.","PeriodicalId":15762,"journal":{"name":"Journal of Environmental Science and Technology","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73517509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to investigate the thermal comfort situation in Ilam city and providing construction solutions appropriate to the climate of this city.Method: The research method in this paper is based on scientific research and simulation. In order to achieve the architecture-compatible architecture of the climate in the city of Ilam, a 28-year statistical analysis (1988-2016) of the city's synoptic station, the criteria presented in four thermal comfort indicators have been used. Based on Mahani and Givoni indices, the results and strategies for reducing energy consumption of buildings are presented. The Design Builder simulator was used to determine the quantitative effect of the proposed solutions by thermal comfort indicators.Results: By using the Mahani and Givoni Indicator's solutions and with passive solutions, the building can be in the comfort zone for eight months from the year of the day and five months from the year without any energy consumption. In addition, building orientation, the relative percentage of openings and the use of heavy materials in walls and ceilings have the greatest impact on reducing the energy consumption of buildings.Conclusion: Energy savings plans that are possible in the early stages of design (building orientation, openings) will result in a 20% reduction in energy consumption, according to the Mahani and Givoni indicators. In addition, replacing heavy materials instead of materials in common building walls can reduce energy consumption by 39%.
