Modeling Tip

5-Minute ASOS Data in AERMINUTE

AERMINUTE is the pre-processor program which reads wind data from Automated Surface Observing System (ASOS) stations in the United States and prepares hourly-averaged wind speed and direction values. Up to now, AERMINUTE only read 1-minute data records in a specific format (TD-6405).

The US EPA recently updated the AERMINUTE executable (dated 15272). This update now allows modelers to supplement the record with 5-minute ASOS wind data to fill in gaps in the 1-minute data records. Lakes Environmental has added this AERMINUTE update to the latest release of AERMET View (Version 9.1).

To incorporate 5-minute data into an existing AERMET View project, follow these simple steps:

Step 1. Open your AERMET View project by double-clicking the .amf file

Step 2. Select the ASOS 1-Minute tab from the Surface display. Select the AERMINUTE button to open the AERMINUTE Utility.

Step 3. In the Utility, select the Specify 5-Minute ASOS Wind Data (TD-6401 / DSI-6401) tab. AERMINUTE is now capable of reading 5-minute ASOS wind data in TD-6401 format from the U.S. National Centers for Environmental Information (NCEI, formerly NCDC). AERMET View includes a link to NCDC’s data archive to retrieve the necessary files. Press the Download Files button to open the link to NCDC’s FTP site.

Step 4. Select Load 5-Minute ASOS Files to begin downloading the files needed for your project. Files are named by station callsign, 4-digit year, and 2-digit month. This example uses data from Reno, NV (KRNO) for the full year 2010 (201001 – 201012).

Step 5. AERMINUTE will prepare comparison files for the 1-minute & 5-minute data. These files are enabled by default in the AERMINUTE Utility. Once complete, you can click the Preview icon to view these files and see where the 5-minute data is incorporated.

Step 6. You’re ready to run! Click Process to run AERMINUTE. Once you’re done reviewing the output, click OK to exit the Utility. The file will now indicate that 5-minute data was used.

AERMINUTE produces an hourly data file which is automatically incorporated to your AERMET View project. You can also view a summary file of the hourly averages calculated in the program.

Delhi Government’s Formula to Check Pollution Level: Odd, Even Number Vehicles on Alternate days from January 1

December 5, 2015 - NEW DELHI - A day after the Delhi High Court observed that the current air pollution levels in the national capital were akin to "living in a gas chamber", the Aam Aadmi Party (AAP) government, Friday, announced stringent measures to bring the situation under control.

The biggest of the proposed measures is that vehicles with odd and even registration numbers will be allowed on alternate days from January 01, 2016.

While Paris Focuses on Climate Change, Air Pollution Kills 400,000 Europeans Per Year

December 5, 2015 - In Wieliczka, near Krakow, a handful of locals have gathered in a hotel conference room to bemoan air pollution. One woman complains of sinus problems caused by soot; another worries about her children playing outside. A man grumbles that police rarely prosecute residents for burning rubbish. It is a tiny gathering compared with the huge climate-change conference that kicked off in Paris on November 30th. But the issue is as big as the sky.

Europe’s air is less corrosive than it once was, and much less foul than China’s or India’s. Industrial decline and clean-air policies since the 1950s have brought levels of many pollutants, such as sulphur dioxide, fine particulate matter (a dust that can irritate lungs), and nitrogen oxides down over the past few decades. Yet more than 400,000 Europeans still die prematurely each year because of air pollution, according to the European Environment Agency. In 2010 the health-related costs were thought to be between €330 billion ($437 billion) and €940 billion, or 3%-7% of GDP.

Congress Passes Resolutions to Block 'Crushing Regulations' Of EPA's CPP

December 2, 2015 - The U.S. House of Representatives has passed two resolutions to block the U.S. Environmental Protection Agency's (EPA) Clean Power Plan regulations for both newly constructed and existing power plants.

S.J. Res. 24, sponsored by Sens. Shelley Moore Capito, R-W.Va., and Heidi Heitkamp, D-N.D., covers existing power plants, and S.J. Res. 23, sponsored by Senate Majority Leader Mitch McConnell, R-Ky., and Sen. Joe Manchin, D-W.Va., covers new power plants.

Before moving to the House, these resolutions of disapproval passed the U.S. Senate in mid-November.

Taiwan EPA Announces Draft Bill Aimed at Poor Air Quality

November 18, 2015 - Taiwan’s Environmental Protection Administration (EPA) yesterday announced a draft emergency response measure aimed at combating air pollution, which would limit the use of vehicles, prohibit some outdoor events and reduce factory emissions by 40 percent when pollution reaches hazardous levels.

The air pollution emergency response draft act concerns levels of PM2.5 — fine particulate matter under 25 micrometers in diameter.
