Neph Data Collection Statistics (Oct ’16 – Sep ‘17)
Site Percent Data Collected
Acadia 96.2
Big Bend 98.4
Glacier 99.6
Great Basin 99.4

Neph Network Enhancements • Communications at all sites have moved to cell or satellite modem
• New AQ shelters at Mammoth Cave (Oct 2016) and Acadia (Sep 2017)
• Arizona DEQ is expected to donate more nephelometers and datalogging systems to NPS – Several “complete” systems anticipated – Funding in this year’s contract to build up 2 systems – Anticipate 6 or 7 sites to be operating with upgraded logging systems by next year
