✦ Synopsis

Many data acquisition systems used in meteorological field studies have digital clocks which indicate true time in hours, minutes, and seconds. This paper describes a circuit which adds the date to the time indication, automatically increments it at midnight, and outputs to the data logger.

The Julian Day Indicator has operated without trouble during a five-month field measurement period. By providing a positive identification of each data scan it simplified computer reduction of the micrometeorological data. The parts required for the device can be purchased for less than $100 exclusive of power supplies.

## Abstract Detailed studies of seasonal patterns of karst processes are rare in remote regions with limited winter access. An important aspect of erosional and environmental processes is how these change over time, and how they relate to annual cycles of temperature, precipitation and runoff. Such
