COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.
Monteith () has suggested the scales shown in Figure V1 involving the coupling of the surface vegetation to the atmosphere. On the continental scale the location and extent of the major plant biomes may be determined by the general circulation of the atmosphere as well as by the space and time variations of the principal energy and moisture factors of climate.

The problem of estimating evaporation from water surfaces and evapotranspiration (ET) via plants is addressed in this volume. The use of climatic data is stressed. Recent developments that are covered involve both direct estimation of evapotranspiration and the use of an intermediate step of calculating reference crop evapotranspiration.
Abstract. This Chapter describes approaches for estimating growth and yield of tropical forests based on climatic data, which are available now for most of countries in form of a time series, a subject of very high interest for the tropics in the light of most of species lacking annual by: 2.
IIT mimics point-intercept field-sampling methods using remotely sensed data, “virtual” points along transects, and a simple and intuitive interface-to-estimate cover.
Three main cover categories are used: noncanopy (rock, litter, soil, and lichens), herbaceous cover (grass and forbs), and woody canopy (subshrub, shrub, tree, and succulent). Linear trend analysis and seasonal trend analysis are performed on gridded data of vegetation, rainfall, solar radiation flux, and air temperature, in order to examine the influence of the past three decades of climate variability and change on the Sahelian vegetation dynamics.
Per-pixel correlation analyses are conducted on annual and monthly data, and analyses of change in the potential Cited by: Wildlife, fire and future climate: a forest ecosystem analysis is written by an experienced team of leading world experts in fire ecology, modelling, terrain and climate analysis, vegetation and wildlife habitat.

climatic layers; potential natural vegetation; hydrology and water dynamics; Data can be viewed and downloaded via the App. You can also publish your own global layer (e.g. environmental layers at resolutions from m to 1 km for a global land mask) or help make better Open GeoData by contributing your own training data to LandGIS.
Weather Bureau Class A Pan evaporation was originally used as the reference for natural vegetation. Starting in the early s, the Priestley-Taylor method became popular for estimating natural vegetation ET because it required less input data.
The Jensen-Haise and Blaney-Criddle methods have also been used as references (Jensen et al. The natural salt meadows of Tilopozo in the hyperarid, Atacama Desert of northern Chile, which are located at approximately m above sea level, are under pressure from industrial activity, and cultivation and grazing by local communities.

This book assesses capabilities of data mining algorithms for spatial modeling of natural hazards in different countries, consists of landslides and earthquake disasters, includes flash flood and land subsidence research, and focuses on climate change, forest fire, land fire and drought subjects.

It is also a continent facing potential problems due to increasing resource demand in combination with climate change-induced changes in resource supply. Quantifying the pools and fluxes constituting the terrestrial African carbon cycle is a challenge, because of uncertainties in meteorological driver data, lack of validation data, and Cited by: Climatic and edaphic controls over tropical forest diversity and vegetation carbon storage with the first vegetation map of the area.

Recent scientific advances in ecological and natural resources research need to be incorporated into mathematical and statistical models of vegetation dynamics. Predictive models are a valuable component in strategic planning for natural resource management at the level of the National Forest and at the national level for all branches of the Forest Service.
The range of climatic conditions determined using the interpolation surfaces was much greater than had previously been estimated.
For example, Boland et al. () estimated the range of mean annual rainfall to be mm and the mean minimum of the coldest month to be °C. As Golfari and others have noted, estimating conditions within the natural distribution is only the first stage. Vegetation condition depends on a series of factors.
Its sudden changes are on the increase; uncertainty linked to climatic conditions, high levels of vulnerability, and food shortage in politically unstable areas, such as, the Horn of Africa (Eerens et al., ).

Quantitative estimation of climatic parameters from vegetation data in North America by the mutual climatic range technique The mutual climatic range (MCR) technique is perhaps the most widely used method for estimating past climatic parameters from fossil assemblages, largely because it can be conducted on a simple list of the taxa present in.
Another aspect is understanding the influence of natural climatic drivers on vegetation phenology. Although, several studies have shown the relationship between the phenological patterns of the African vegetation and climatic drivers, precipitation-driven studies are more numerous than temperature and solar radiation studies (see Section Cited by: Estimating Forest Tree Carbon using Remote Sensing Data and Techniques - Adeel Ahmad - Master's Thesis - Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies - Publish your bachelor's or master's thesis, dissertation, term paper or essay.

The basic data used in the study were: The daily meteorological data of year - The experimental field area - Soil data - Crop data.Groundwater Dependent Ecosystems (GDEs) are increasingly threatened by humans’ rising demand for water resources.
Consequently, it is imperative to identify the location of GDEs to protect them. This paper develops a methodology to identify the probability of an ecosystem to be groundwater dependent.
Probabilities are obtained by modeling the relationship between the known locations of GDEs Cited by: 7.The study region was divided into ´ sq km cells defined by satellite sensor pixel size.
