Emergency Response Weather Stations for Professional Responders

The nature of emergency response dictates that emergency weather stations must be easy to deploy and operate, endure rough handling and harsh conditions, and provide reliable, site-specific weather data.

WEATHERPAK® is the only weather station that meets the requirements of Hazmat/WMD response operations and withstands the associated rigors. It is impervious to airborne chemicals and designed to be deployed in or near the hot zone.

The Critical Role of WEATHERPAK®

Hazmat weather stations are typically used in two ways: either as a rapid response tool following the release of hazardous materials, or for routine monitoring of critical infrastructure (e.g., chemical, petroleum, water treatment facilities, etc.).

In either case, site-specific weather data can be viewed on the display screen and simultaneously fed to plume dispersion software (CAMEO®*/ALOHA®*, PEAC-WMD®**, COBRA, etc.). These programs graphically display a chemical plume overlaid on a map of the immediate vicinity, which allows Incident Command to make confident decisions based on reliable data.

WEATHERPAK measures wind speed and direction (every second), temperature, humidity, and barometric pressure. Then it computes the values prescribed by the US EPA to properly update a plume model. The data is then transmitted to a computer from one to five miles line-of-sight via radio.

Features Common to all Portable WEATHERPAK® Emergency Response Weather Stations

  • WEATHERPAK is primarily designed for portable use — It is self-contained with no cables, connectors, or switches.
  • Easily deployed — WEATHERPAK can be set up in less than 60 seconds — without tools — by a responder wearing full protective gear and breathing apparatus.
  • Automatically updates CAMEO®*/ALOHA®*, PEAC-WMD®**, CoBRA and other chemical plume modeling software.
  • Ultrasonic Wind Sensor — A rugged, no-moving-parts wind sensor that is very accurate and does not require periodic calibration.
  • Computes five-minute running averages and wind stability calculation as required by the EPA.
  • Automatically aligns to True North. Internal electronic compass eliminates alignment errors.
  • Built of a T-6061 marine grade aluminum, WEATHERPAK will survive a six-foot drop to concrete, is submersible for decontamination, and contains no plastic or PVC structural components.


On-site, real-time weather data for chemical, biological, and radiological response

The WEATHERPAK RESPONSE hazmat weather station incorporates all of the features above that make WEATHERPAK the number one choice of professional responders, and much more:

  • SmartDetect™ Firmware — Automatically networks and displays data from up to 20 additional WEATHERPAK hazmat weather stations in the vicinity, from which the operator can select the most representative data to send to the model.
  • — Features touch screen access to data from any WEATHERPAK in the vicinity.
  • Integrated GPS — Provides the location of other WEATHERPAK RESPONSEs in the vicinity, and also automatically applies the compass declination, providing accurate wind direction data regardless of where the system is used or transported.
  • Designed for use in or near the hot-zone. Data is transmitted via radio (UHF or Spread Spectrum) to the plume model.

New INTERCEPT® Display for WEATHERPAK® RESPONSE Weather Stations

User Features:

The touch screen on the new RESPONSE INTERCEPT® display features Coastal's proprietary INTERCEPT® data collection, display and forwarding software. All weather data is quickly accessed through tabs at the top of the easy-to-use interface.

  • Two built-in audio alarms
  • Automatic transmission of RESPONSE data to plume modeling software
  • Selectable day or night viewing screens
  • Automatic boot-up
Station Screen

In the Observer section the Station screen is the most important and most frequently used information screen. It displays the data received from the selected WEATHERPAK. (There are three station tabs in this example).

Weather Summary Tab

The Weather Summary tab displays data from other WEATHERPAK systems detected in the vicinity, in a columnar fashion. If any of the remote systems are WEATHERPAK RESPONSEs, the relative position (direction and distance) for those weather stations will also be displayed.

Maintenance Dashboard

The Maintenance Dashboard tab shows the operational status of a network of weather stations.

Status Screen

From the Data Display tab in the Maintenance section, users can create simple alerts based upon a single sensor's data, or more complex alerts using data from multiple sensors.

Status Screen

When an Alert condition exists, the corresponding field on the Observer station screen is highlighted.

Active Screen

User customizable Log files are stored for 30 days and can be exported through the user interface.


Graph Screens include wind direction and speed, temperature, barometric pressure, and humidity. Users can view hourly and daily graphs, scroll back through the last 24 hours, or select a specific date (or range) to graph. The running hourly display is updated once per minute.

Display Specifications:

  • 10.1" WXGA TFT LCD with LED backlight (1280 x 800 resolution)
  • *Intel® Celeron® processor N3060 2 cores (up to 2.48 GHz) with 8 GB system memory
  • Weight and dimensions:
    • 2.38 - 4.8 lbs (depending on radio)

  • Integrated GPS — Provides the location of other WEATHERPAK RESPONSEs in the vicinity, and also automatically applies the compass declination, providing accurate wind direction data regardless of where the system is used or transported.
  • Designed for use in or near the hot-zone. Data is transmitted via radio (UHF or Spread Spectrum) to the plume model.



Power-over-Ethernet (PoE) — A structure mounted station uniquely suited for emergency management applications such as urban networks and monitoring critical infrastructures.

WEATHERPAK RESPONSE is the easiest professional grade weather station in the world to install and maintain. Built-in GPS and an electronic compass automatically align the system to True North, eliminating wind direction errors during installation. One cable provides system power and retrieves the data.

Standard sensors include an ultrasonic "no-moving-parts" wind monitor, air temperature and relative humidity. A barometric pressure sensor can be added to meet your local requirements.

  • Able to quickly create a weather station network anywhere Ethernet access is accessible.
  • Readily adapts to a wide variety of commercially available mounting solutions.
  • Coastal's INTERCEPT® software displays and archives data, and provides alerts and secure controlled data access via the Web.

Coastal's Hazmat History

In 1984, the US National Oceanographic and Atmospheric Administration (NOAA) approached Coastal Environmental Systems with a beta version of the ALOHA plume modeling software and asked if we would build a portable weather station to use with this new tool for hazmat responders. The objective was to deliver on-site data to the responders at the incident scene — surprisingly a revolutionary concept at the time. The system we developed and tested, in cooperation with the Seattle Fire Department, is the foundation of WEATHERPAK® as is exists today.

The first "hazmat" WEATHERPAK was purchased by the Huntington Beach Fire Department (California) in 1988. Since then, Coastal has become the leading manufacturer of emergency response weather stations. WEATHERPAK is now used by hundreds of fire departments, all branches of the US military, and by militaries and emergency management agencies around the world.
