BACKGROUND The transmission of hemorrhagic fever with renal syndrome (HFRS) is influenced by population dynamics of its main host, rodents. It is therefore important to better understand rodents' characteristic in epidemic areas. METHODOLOGY/PRINCIPAL FINDINGS We examined the potential impact of food available and climatic variability on HFRS rodent host and developed forecasting models. Mont...
Depending on the vegetation type, extreme climate and drought events have a greater impact end of season (EOS) start (SOS). This study investigated spatial temporal distribution characteristics grassland phenology its responses to seasonal changes in Sichuan Province from 2001 2020. Based data 38 meteorological stations Province, this calculated 15 indices recommended by Expert Team Climate Cha...
Nowadays, climate change and heat extremes are becoming highly challenging problems in many cities across the globe. One of solutions to overcome this problem is use vegetation, and, particular, extending range overgrown areas, which sometimes referred as “urban green areas.” In paper, moisture condition its mitigating effect on Land Surface Temperature urban areas were examined Warsaw, Poland,...
Satellite-based drought indices have been shown to be effective and convenient in detecting conditions. The temperature vegetation dryness index (TVDI) is one of the most frequently used indices; however, it not suitable for areas with high fractional cover (FVC). In this study, a modified (mTVDI) was constructed by using multispectral (MVDI) proposed PROSAIL simulation water stress experiments...
تحقیقات نشان میدهد که مخازن بزرگ آبی، مانند یک سطح تبخیری بزرگ عمل کرده و در مناطق با رطوبت پایین باعث افزایش دمای سطح میشوند. از آنجا که سدهای بزرگ دارای اثرات منفی بلندمدتی بر روی اقلیم محلی هستند، ضروری به نظر میرسد که پیش از احداث این گونه سدها در اقلیمهای نیمه خشک مطالعات بیشتری در رابطه با مکانیابی احداث آنها انجام شود. سنجش از دور ابزاری قدرتمند در مطالعات زمانی اقلیمهای خرد و کل...
Land use/land cover (LULC) change and climate are thought to be closely related mutually influential, especially in contexts where land is converted for urban expansion or agriculture. We represent a first attempt specify the relationship between LULC dryness region of Vietnam that profoundly affected by change. Using temperature–vegetation index (TVDI), we specified relationships changes under...
da sua demanda hídrica é fundamental para o manejo adequado, podendo-se, a partir dela, avaliar e mensurar desenvolvimento morfofisiológico das plantas, acompanhando seu crescimento ao longo de todo ciclo. Existem diversos parâmetros biofísicos que estimam as condições hídricas cultura, dentre eles Temperature Vegetation Dryness Index-TVDI. O objetivo deste trabalho utilizar TVDI em áreas produ...
