If you walk the halls of NASA’s research facilities , you will likely overhear scientists talking about algorithms —the detailed, often repetitive sequences of rules used in mathematical calculations or other problems. While algorithms are used in other contexts, they are most widely used in computer programming. Almost all of the 2,400 earth science data products distributed by NASA—from precipitation products produced by the Global Precipitation Measurement (GPM) mission to aerosol products from the Moderate Resolution Imaging Spectroradiometer (MODIS)—are dependent on sets of algorithms that help transform raw observations into data products that are useful to scientists. The concept of an algorithm has a long history that involves the invention of numerals, mathematics, and computers. The word itself has an interesting origin story that traces back to Khwãrezm (which h...
