Title/Titre: Oregon Scientific WMR968 Cable FreeTM Weather Station Author/Auteur: Sgt. Serge Larocque & Sgt. Carl McDiarmid
Since approximately April 2003, the four regional CBRN trained RFISS members have been in possession of and are testing the Oregon Scientific WMR968 Cable FreeTM Weather Station. The CBRN personnel found a requirement for a weather station capable of providing real time local meteorological information at a potential CBRN crime scene. This information could assist CBRN personnel and local incident commanders in determining the extent of exclusion zones based on this information and the type of threat encountered. Historically, these types of instruments have been very costly and their ease of operation difficult. The military component of the National Chemical Biological Radiological Nuclear Response Team recommended that we investigate the Oregon Scientific products and in particular the WMR968. Since testing, the WMR968 has been found to be a very beneficial piece of equipment. It is felt that the low cost and the ease of operation would also make it a valuable and affordable tool for any Forensic Identification Section. The WMR968 is designed to provide the following five weather elements: Air temperature (inside / outside) Relative humidity (inside / outside) Barometric pressure Wind speed and direction Rainfall However, from these five basic measurements, the WMR986 and some optional software from Ambient Inc., will provide comprehensive reports that will provide approximately 38 measurable values, trends, maximums or minimums; ie: wind chill, dew point, gusts, etc. (see Appendix B) The system consists of five main components: 1) Main Unit (WMR968) - This unit is the main recording and display device for the system. It will support up to seven remote devices and three optional thermo or thermo-hygro sensors. The back light capable touch screen allows for the selection of the standard units of display, depending on the specific measurement being observed. For example, temperature may be displayed in degrees Celsius or Fahrenheit, wind speed can be displayed in kph, mph, mps, knots, etc. (Dimensions in inches: 8.5 x 1.75 x 5.5)

These records can be captured on a user identified time frame and can be as frequent as every minute. The record storage capacity is limited to a total of 20,000 records. Based on a frequency of one record every five minutes, that would equate to continual weather recording for 69 days.

The value of this weather station and software combination is very apparent in non-CBRN applications within Forensic Identification Services. The capability of recording of actual on site weather conditions for outdoor murder investigations would be beneficial for forensic anthropology examinations. The rental or acquisition of mini mets in the past has been very expensive and this alternative is very attractive. The only drawback to the system is the requirement of a laptop to utilize the software required to achieve this capability. RECOMMENDATION: After operating and evaluating the Oregon Scientific WMR968 Cable FreeTM Weather Station and the Ambient Virtual Weather Station Pro Edition software, it is felt that the acquisition of this type of instrument would be beneficial to some Forensic Identification Sections. Having an affordable weather station for major crime scene investigations makes it a valuable tool worthy of consideration at budget time. If you should have any questions concerning the weather station or associated software, please do not hesitate in directing questions to the writers noted below. Sgt.
