The data visualization tool for My NASA Data, the Earth System Data Explorer, provides access to dozens of datasets. It can be used to produce maps, time series plots, and data tables which can be downloaded. 

Scientists and engineers develop the procedures for their research and then carry out their investigations in a variety of environments (i.e., in the lab, outdoors, with others, as well as independently).  They must plan in advance their criteria for the data they wish to collect, the condit

The products of science are explanations and the products of engineering are solutions.
