Getting started First, get all the files, either as a zip archive or a gzipped tar-file and unpack them. If you are unpacking the zip file MAKE SURE YOU ALSO UNPACK SUBDIRECTORIES! Now, start up Matlab (version 5 or higher). Make sure that the toolbox is in your path. Alternatively, if you have unpacked them into directory /users/rich/m_map (and /users/rich/m_map/private), then you can add this to your search path: path(path,'/users/rich/m_map'); or addpath /users/rich/m_map To follow along with this document, you would then use a Web-browser to open file:/users/rich/m_map/map.html, that is, this HTML document.

Note: you may want to install M_Map as a toolbox accessible to all users. Rehash toolboxcache Instructions for installing the (optional) high-resolution bathymetry database are given in Section 9 , and instructions for installing the (optional) high-resolution GSHHS coastline database is given in Section 10 . To see an example map, try this: m_coast('linewidth',2,'color','r'); 2. Pubs.GISS: NASA Goddard Institute for Space Studies Publications. Get Data. Get Data. CIMIS - [ Welcome ] NCDC: Climatic Extremes and Weather Events. Empirical evidence for a recent slowdown in irrigation-induced cooling -- Bonfils and Lobell 104 (34): 13582 -- Proceedings of the National Academy of Sciences. Rapid changes in land use, including deforestation, urbanization, and irrigation, are widely acknowledged to influence regional scale climate (1–4). Urban areas occupy ≈2% of the Earth's land surface (5), and considerable efforts have been devoted to estimating the contribution of urbanization to observed warming in certain regions (6).

In contrast, although ≈2% of global land surface is irrigated [≈17% of the 15 × 106 km2 of world's agricultural land (7)], the role of irrigation in observed temperature trends has been less a subject of investigation. Because the surface cooling that accompanies evaporation of irrigation water seems negligible in comparison with global greenhouse warming, and because the positive radiative forcing associated with the increase in water vapor is small (8), influences of irrigation are often ignored in climate projections and often neglected in the process of detecting human-induced climate change (9). Observed Irrigation and Temperature Time Series. 6(c). Energy, Temperature, and Heat. So far we have learned that energy can take on many forms.

One important form of energy, relative to life on Earth, is kinetic energy. Simply defined, kinetic energy is the energy of motion. The amount of kinetic energy that a body possesses is dependent on the speed of its motion and its mass. At the atomic scale, the kinetic energy of atoms and molecules is sometimes referred to as heat energy. Kinetic energy is also related to the concept of temperature. Some other important definitions related to energy, temperature, and heat are: Heat Capacity - is the amount of heat energy absorbed by a substance associated to its corresponding temperature increase.

Figures 6c-2 and 6c-3 show the net absorption and release of latent heat energy for the Earth's surface for January and July, respectively.
