Automated Correction Loader (ACL)

Automated Correction Loader (ACL) is UNIX-based software that automatically computes and uploads water-quality (WQ) corrections to ADAPS. As users lock site visits, ACL retrieves water-quality data from NWIS SiteVisit and computes fouling and drift errors. The errors are compared to TM1-D3 criteria and loaded to ADAPS automatically. The user receives an email for every site visit that ACL processes. Users are encouraged to evaluate the data corrections as part of the continuous records process for WQ records. ACL is a component of the Continuous Water Quality Committee's (CWQC) recommended path for WQ records. ACL was developed by Eric Kerner, Steve Brady, and Pat Rasmussen (USGS, Lawrence, KS), with support from the CWQC. It is expected that the upcoming release of AQUARUIS will either accommodate or supersede ACL.

Latest ACL features include:

• Processes every 15 minutes.
• Configuration file editor.
• Script to initialize WQ site information and DDs from NWIS.
• Data correction customization through configuration files.
• Computed data corrections are evaluated with criteria in TM1-D3.
• Emailed report list data corrections and whether or not they're loaded to ADAPS.
• ACL will not overwrite existing data corrections.
• ACL can be configured to process the affected time-series record.
• The Water Science Center controls which sites ACL processes.
• ACL evaluates SC, pH, DO, and turbidity parameters.
