Progress - Rain Guages

Part of the difficulty in measuring rainfall comes from the variability in rain guages.  Rain guages may very in shape, size, maintainence, and temporal resolution among other factors.  The five images below demonstrate this variability.

Progress - Remote Sensing

Although rain guages are extremely effective in determining rain fall levels for a specific area, in sparsely populated areas such as the Amazon, remote sensing is a far more viable approach.
