2 Data Acquisition & Management Systems: A Small District’s Perspective (or how I became a kid again at 60)

3 NSCAPCD Monitoring Network 3 PM10 Aerometric Sites w/ MetOne BAM ’s and Agilaire ESC 8832’s 1 Ozone Aerometric Site w/ Redundant Teledyne API 400E Ozone Analyzers and Agilaire ESC 8832’s 3 DSL Lines w/ CISCO VPN Firewalls 1 Satellite Link w/ CISCO VPN Firewall Agilaire AirVision © Software on a Virtual Server w/ Separate SQL Database

4

5 Agilaire AirVision Data Acquisition and Mgt Software AirVision Suite (Version ) with : – BAM Direct Poll Option (Digital) – File Import Configuration Option – ADVP (Advanced Data Validation Program) Option – Parameter Equation Math Pack Option – Precision & Accuracy Reports Option

6 Why Sample Digitally? Avoid DAC/ADC Conversion Errors Data Reliability Enhanced Instrument Diagnostic Information

7 Available Digital Parameters for API 400E Ozone Analyzer

8 Analog vs. Digital

9 Use of DMS Data in Instrument Diagnostics API 400E Daily Zero-Span Drift and O3 Gen Table Cal Points

10 Daily Ozone Calibration

11 Graphic Representation of May 7 Zero-Span Note lack of feedback response on ozone concentration

12 Normal Daily Zero-Span Note beginning concentration level and end concentration level

13 Real Time Analyzer Manipulation Minute Time Series Graph of O3 Gen Drive (mV), O3 [ppb], and O3 Gen Ref(mV) from API 400E O3 Gen Cal Data Showing APICOM connected to analyzer for control & Hyperterm open on Real-time Data Display

14 O3 Gen Cal Graph from May 8 Note O3 Gen internal calibration points relative to ambient levels required for precision checks

16 BAM Data File Import Template: Error Code Parsing

17 Advanced Data Validation Processor Task: Poll Raw Data from Sites ↓ AV Database Task: Apply ADVP Rules→ Raw Data Flags Null Codes Notifications

18 ADVP Editor

19 BAM Error Messages From: To: George Erdman; Jessica DePrimo; Randall Woodward; Alex Saschin Subject: BAM Error Flag "D" - BAMFLAG_D 5/1/ :00:00 - 5/1/ :00:00 1h Date: Tuesday, May 01, :04:37 PM Importance: High Message: The BAM Station below has recorded an Error Flag "D" The error indicates that the reference membrane span check measurement (m) for that hour was out of agreement with the expected value (ABS) by more than ±5%. Applying Actions on reading: Healdsburg:BAM01_PM 10:001h at 5/1/ :00:00 with value > Annotation Added "Ref Membrane BAM CAL Error; does NOT invalidate hourly data" > Add Flag ? From: To: George Erdman; Jessica DePrimo; Randall Woodward; Alex Saschin Subject: BAM Error Flag "L" - BAMFLAG_L 5/1/ :00:00 - 5/1/ :00:00 1h Date: Tuesday, May 01, :04:33 PM Importance: High Message: The BAM Station below has recorded an Error Flag "L" The error occurs any time power is cycled or lost, even momentarily. See manual Section 6.5. Applying Actions on reading: Healdsburg:BAM01_PM 10:001h at 5/1/ :00:00 with value > Annotation Added "Power Failure Error" > Apply Null Code AV > Add Flag P
