Study Description

In 2004, NOAA published the Atlas 14 Vol 2 for the mid-Atlantic States. Since publication, the amount of available has increased, both in the number of stations and their record lengths. For stations used in Volume 2, two decades of data have accumulated since the completion of the current estimates. Also, many stations that were not retained for analysis in Volume 2 due to short records will be considered for Volume 13. This increase in data could have a considerable effect on precipitation frequency estimates.

Objectives

The purpose of this project is to update precipitation frequency estimates for Delaware, Maryland, North Carolina, Pennsylvania, South Carolina, and Virginia published in NOAA Atlas 14 Volume 2. Like previous NOAA Atlas 14 volumes, the estimates and associated bounds of 90% confidence intervals will be provided at 30 arc-sec resolution for durations of 5-minute through 60-day at average recurrence intervals (ARIs) of 1-year through 1,000-year. The study results will be published as NOAA Atlas 14 Volume 13, a wholly web based publication available at Precipitation Frequency Data Server (PFDS).
