... UNIX^2.2

In the latter half of the 1980's, SUN 3/50 workstations were introduced which ushered in a new era of model development. Before this, code development was done without the aid of editors or utilities like UNIX grep.

... data^3.6

All DATABASE data consists of a header record preceding each data record. Included in each header is a time stamp. It contains the time corresponding to the instantaneous time at the end of the averaging period. It also contains a period which refers to the length of the time average. As an example, a time stamp of: m/d/y= 2/ 1/1900,h:m:s= 0: 0: 0. points to the beginning of the 1st day of Feb on year 1900. A period of 31 days for this record means that the data is average over the preceding 31 days; i.e, it is an average for January.
