| Lineage information for: dataset |
|----------------------------------|
| Lineage Statement                | The data in this file are a combination of original observations of hourly and daily accumulated precipitation. Precipitation values are checked and edited as necessary by an automated and manual edit. |
| Processing Steps                 | - Fischer-Porter precipitation gauges record data on punched paper tapes. A device known as the Mitron reader translates the data at NCDC. The Universal Rain gauge records data on paper charts. The precipitation recorded on the charts is then digitized. The data from the Surface Climate Information Archive and Dissemination System (SCIADS) or primary stations is also entered. |
| Source Datasets                  | - Data from weighing rain gages, Fischer-Porter gages, Universal rain gages and in recent years, more modern measuring equipment in conjunction with automated recording sites   - Description of Source: Keyed and digitized rain gage forms (historic) and digitally captured precipitation from automated stations (modern).
  - Temporal extent used: 1940-01-01 to 2013-12-31 |

| Processing Steps                    | - 2015-04-22T00:00:00 - NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015. |
