About this file
This document is a detailed design specification for the NPS Portable Ozone Monitoring System (POMS) Mark II, a self-contained environmental monitoring unit developed for the National Park Service. The system is designed to measure ozone and meteorological parameters in remote park locations without available power or phone access. Key components include a 6' tripod-mounted system with solar panels, a 2B Technologies ozone analyzer, Campbell 23X datalogger, Orbcomm transmitter, and various meteorological sensors (wind speed/direction, temperature, relative humidity, solar radiation, and precipitation).
The POMS II is fabricated by a field support contractor, shipped disassembled, and can be assembled on-site by a technician. The ozone analyzers are calibrated at the start and end of the monitoring season (May to September), with daily zero checks and automated data transmission via satellite modem approximately every hour. The system offers flexibility in configuration, with options for different pollutant measurements, weather sensors, communication methods, and power sources. The design emphasizes portability, minimal operator support, and reliable operation in remote environmental monitoring scenarios.

NPS Portable Ozone Monitoring System (POMS) Mark II Design
The POMS II is a revision to the original design that is lighter, cheaper, and without the filter pack measurement capability. The purpose is to be a self-contained unit that can measure ozone and meteorological parameters in park locations without available power and phone.
Concept diagram
Figure 1.
Design Considerations and Assumptions
The primary design considerations are:
• UPS shippable in several boxes
• Can be installed by one field technician
• Tripod mounting system with 6’ mast for instrumentation
• Solar powered; separate skid-mounted system (2 panels with controller and batteries)
• Contains one (1) 2B Tech ozone analyzer
• Campbell 23X datalogger and Orbcomm transmitter
• Meteorological sensors
- Wind speed and direction at 6’ mast height
- Temperature and relative humidity (naturally aspirated) at 4’
- Solar radiation at 6’
- Precipitation (tower mounted at 3’)
• Weather-proof ventilated enclosures for 2B, datalogger, and power system
• All systems will run at ambient temperature
The systems are self contained and able to run reliably with minimum operator support for the ozone season (May to September). Daily zeros are automatically performed on the 2BTech analyzer to assess its operational status. The site operator is required to change the ozone inlet filter approximately every two weeks. If a 2B Tech analyzer failure occurs, the site operator will be able to easily replace the 2B with a backup operational unit shipped to the park.
Figure 2. Photo of a POMS II. The main unit is a tripod with the meteorological sensors and two instrument boxes. The solar panel and battery box are in a separate frame.
Figure 3. The 2B Technologies ozone analyzer has its own instrument case.
The analyzer folds up into the box to close the cover. A sun shade is above the box and an internal fan inside is thermostatically controlled.
Figure 4. The Campbell Datalogger, Orbcomm satellite modem, relays, and electrical systems are in the second instrument box.

The POMS II units are fabricated by the field support contractor, tested and shipped to the monitoring sites in several boxes disassembled. A technician, or in rare cases a site operator, assembles the POMS unit on-site and calibrates the weather sensors.
The 2B Tech ozone analyzers are calibrated at the field support contractors lab at the beginning of the season and again at the end of the season. Daily zero checks and instrument parameter data are used to assess the function and health of the instrument. All data is sent through the Orbcomm satellite modem and placed on an ftp site for retrieval by the field support contractor. Update transmissions are approximately hourly. Communication is one-way. The datalogger also retains the data and can be polled at the end of the season to recover all data.
The 2B Tech ozone analyzer has an internal datalogger that retains ozone, case temperature, and instrument pressure information. This data can be retrieved through a serial port to a PC computer using the Windows HyperTerminal program.
