Continuous Hydrologic Instrumentation Monitoring Program (CHIMP)Continuous Hydrologic Instrumentation Monitoring Program (CHIMP) is an electronic version of the USGS Continuous Water-Quality Monitor Field Form [165KB PDF] for use on (personal digital assistants (PDAs) with the PocketPC/Windows Mobile operating system (or PC with use of an emulator). CHIMP is used to collect data about monitor fouling and calibration data during site visits to active continuous water-quality monitors. CHIMP is a component of the Continuous Water Quality Committee's (CWQC) recommended path for water-quality records. CHIMP was developed by the Field Computing Integration and Support (FCIS) team. ![[ Image: Continuous Water Quality Committee: recommended workflow path. ]](images/chimp.jpg "Continuous Water Quality Committee: recommended workflow path")
Figure 1. Continuous Water Quality Committee recommended path for working with continuous water-quality records. CHIMP allows users to collect before- and after-cleaning, calibration, and final measurements and all associated metadata for any water-quality monitor. CHIMP supports the methods described in USGS Techniques and Methods (TM) 1-D3 (Wagner and others, 2006) for water temperature, specific conductance, pH, dissolved oxygen, and turbidity. Users can also collect measurements for any other sensors (chlorophyll, UV nitrate, blue-green algae, total dissolved gas, etc.) using the "Other" sensor setup option (see user manual [4.3MB PDF]). The resulting XML output can uploaded to SiteVisit [510KB PDF] and can be viewed in a field sheet format using the CHIMP stylesheet. Data corrections derived from site-visit information are easily and automatically computed for specific conductance, pH, dissolved oxygen, and turbidity when CHIMP is used in conjunction with Site Visit and the automated correction loader (ACL). DownloadsAny USGS user can download the latest version of CHIMP and the installation instructions.
