Asian Air Pollution Affecting World's Weather

Originally Posted at: January 21, 2014 Asian Air Pollution Affecting World’s Weather Extreme air pollution in Asia is affecting the world’s weather and climate patterns, according to a study by Texas A&M University and NASA’s Jet Propulsion Laboratory researchers. Yuan Wang, a former doctoral student at Texas A&M, along with Texas A&M atmospheric sciences professors Renyi Zhang and R. Saravanan, have had their findings published in the current issue of Nature Communications. Satellite photo shows huge air pollution clouds at far left. Japan is on the right. (Photo: NASA JPL) Using climate models and data collected about aerosols and meteorology over the past 30 years, the researchers found that air pollution over Asia – much of it coming from China – is impacting global air circulations. “The models clearly show that pollution originating from Asia has

Are You Ordering the Correct Instrument For Your Application?

 Correct Instrument for the Best Results  Met One Instruments, Inc. manufactures a variety of particulate monitors for indoor/controlled environments and for outdoor ambient air.   Although we diligently ask the inquirer about the application, we don't always get the correct answer.  Misunderstood examples are our Aerocet models 531 and 831 Mass Monitors.  These models are used as indoor or controlled environment monitors.  They should not be used to monitor ambient air.  We often hear it does not correlate to the BAM 1020 or E-BAM.  They may be adjusted using the K-Factor, however, these are not recommended ambient air monitors.  Those wanting to monitor outdoors , please consider the BAM 1020 for regulatory requirements or the portable E-BAM and/or E-Sample r. 

Met One Instruments, Inc. Solutions for Unmanned Aerial Vehicle Test Sites

Met One Instruments, Inc.  Grants Pass, Oregon  USA:  We offer many meteorological and air quality technological solutions for Unmanned Aerial Vehicle programs for commercial, industrial, and military applications.  Please inquire about launch site and downrange systems that provide fast, accurate meteorological data.  Portable and fixed-site systems are available to forecast optimal UAV flight conditions and accurate payload delivery.  (Repost: )   Drones have useful applications for OSU The use of unmanned aerial vehicles (UAVs), sometimes referred to as “drones,” has been the focus of increased recent international attention. It also has captured attention in the Oregon Capitol with the introduction of House Bill 2710 and Senate Bill 524, which would set restrictions on the use of UAVs by law enforcement agencies, and Senate Bill 71, which would regulate the use of drones by


Met One Instruments, Inc. and American Ecotech have supplied the air quality monitoring station and the meteorological sensors and tower to Arizona Clean Fuels – Yuma , ACFY. The installation of this equipment is a critical step for ACFY in obtaining their Class-1, Title-5, PSD Air Permit from the Arizona Department of Environmental Quality. The air quality monitoring station includes two BAM-1020 ’s; one configured to measure PM10, the other configured to measure PM2.5. The meteorological tower is 100 feet tall and uses our 010C and 020C wind sensors, a triple-matched set of 062 differential temperature sensors and the 076B fan aspirated radiation shield.  A second class pyranometer and our 370 rain gauge are also being used on the ACFY site. Here are a few pictures of the Met One Instruments equipment installed at the site and a short video of the erection process of the 100-ft  meteorological tower.

To begin 2014, Met One Instruments, Inc. (MOI) is excited to announce a new corporate partnership to expand meteorological measurement capabilities. Atmospheric Systems Corporation (ASC), of Valencia, California, is a recognized leader in meteorological remote sensing using So und D etection A nd R anging (SoDAR) to measure vertical wind and turbulence profiles. This partnership will enable Met One Instruments and Atmospheric Systems to continue to grow meteorological markets for Air Quality, Wind Energy and Atmospheric Research.   Both companies have seen increased demands for complex systems comprised of complimentary meteorological measurement systems. The companies share mutual clients and complement each other’s sales, service and product development.   ASC’s President, Dr. Ken Underwood, is one of the leading SoDAR experts in the world and has been involved fulltime in SoDAR research, development and manufacturing for over 30 years.   He will continue to d

Why We Use Glass Fiber Filter Tape for Our PM Monitors.

Mr. Serie Jr. volunteers for Envicontrol at Pollutec 2013 and shows his enthusiasm for the MOI BAM 1020. Met One Instruments, Inc. has extensively evaluated several types of Teflon (PTFE) filter tape for use with the BAM product line. As of now, we have never identified any Teflon filter that is superior to the regular glass fiber filter for the BAM application: 11)      The BAMs have a small spot size and a high flow rate. The resulting high pressure drop and high  face velocity is very difficult on the filter material. 22)      Glass fiber material is a depth filter which has extremely high filtration efficiency of greater than 99.999% down to .2 micron particles and even much smaller. Teflon membrane is a porous surface filter which is not as efficient and some particles get through. 33)      Glass fiber material can handle much higher filter spot dust loads before the airflow is restricted. Teflon sometimes blocks the airflow in concentrations l
