The Airvision System Allows the Setup of Sites and Measurements, with AQS Reporting Codes

The AirVision system allows the setup of sites and measurements, with AQS reporting codes for each pollutant. In this illustration, an additional ‘parent’ parameter is set up to link information about each instrument run with the ‘child’ parameters. Multiple POCs for collocated or QA samplers at the same site is also supported.

Once the site / parameter setups are done, the web-based field forms allow for the initial ‘setup’ data to be entered via laptop, tablet, and then final run data can be updated in the record when the sample is retrieved. Forms are specifically designed for different samplers with different fields (PAH, VOC, Metals, PM25, PM10, etc). For example, some instruments use different start/ending meters, flow in different units, etc.

If the system is connected to continuous met data, daily pressures/temps can be drawn into the form as well.

Data from calibrations are also entered on similar forms, and values from the last calibration (slope, intercept, set point) are automatically retrieved. Business logic in the form can perform checks and calculate desired values, such as flow difference, or set points in the calibration form.

Once the laboratory data is available, a delimited data file can be uploaded via the web interface. AirVision provides its Generic File Import Tool (FIT) to configure ‘import templates’ to match a file format to the desired parameters. The system can match values to parameters either by a certain string in each row, e.g.:

Each line contains: Date, Time, Site, Parameter, Value, NullCode, etc

Or, if multiple parameters on each line, by matching row numbers or certain header strings to certain parameters:

If special preprocessing of the file is required to bring it to a layout compatible with the File Import Tool, AirVision’s programming structure allows for this do be done easily and efficiently.

Visualization tools include graphical time-series trends, either in the Sample Data Editor (where values can also be reviewed, add null/qualifier codes, etc) or the Sample Data Graph report. Data can also be exported into CSV format, PDF, HTML, etc. Additional visualization tools may be developed or put into our planned enhancements based on user feedback / input.
