Feeling Patriotic

Another in the long list of reasons why I love this country...

Now what do you want to see?

This is where all the weather apps and websites get their data. They just package it up and add advertising or charge you. You can do this yourself with a computer by getting the data from NOAA and the easy-to-use Panoply software from NASA for free.

* You don't have to use your email address, but it is standard courtesy in anonymous ftp to use your email address as a password so that they can log where users are coming from. For instance, if you are a teacher or student, use your school email address so they can log you as an education user. This is how we discover needs and allocate funding.

The perennial dilemma

Air is a common resource. Each of us suffers from degradation of the air quality, but we have no little control over what others do to the air that we personally breathe.

When people think of the Boulder, they don't often think of air pollution. But, the elevation and topography (mountains to the west and northwest and the Louisville Rise to the east and southeast), and the automobile traffic in this small town, mean that the nose-level pollution in central Boulder is usually higher than the western coastal neighborhoods of Los Angeles. (My doctors had recommended in the 1990s that I move away from Boulder for my health and suggested coastal LA as a good alternative.)

You can't see ozone, but it is created by a combination of automobile exhaust and sunlight, specifically UV radiation.  At high altitudes, we have plenty of UV (and cosmic ray) radiation.

Ozone is a lung irritant.

We can't control sunshine, so the only way to keep the ozone from reaching dangerously high levels is to refrain from driving.  That means you AND me.

But, sensitive people are cautioned from strenuous outdoor exercise during high ozone days.

What does an asthmatic do when an Ozone Action Day is called?  Ride my bike and possibly have an asthma attack?  Drive solo and pollute the air even more?

The combination of pollen and ozone is particularly irritating.  People with pollen allergies can be affected by lower levels of pollen when ozone is present.  The only time I ever ended up in a clinic gasping for breath was when I went for an after work run (in grad school in the 1990s) up Boulder canyon during a day with both high ragweed pollen and high ozone.  I now get allergy shots and that has helped somewhat.  But, I still avoid outdoor exercise when pollens are especially high.

Fortunately, my bike and I can pick up a shuttle bus to work 2 blocks from my condo and be whisked up to the main entrance of Mesa Lab.

So many of my coworkers did the same, we filled up both the front and rear bike racks of the van.

Some even took the RTD bus to meet the shuttle.

The best part of leaving the driving to someone else is that my hands are free to take pictures like this.

The ride home is an 800 foot elevation drop, so it is not the strenuous type of exercise that would be dangerous for me.

Wildfire PSA

With wildfires burning all over the western United States and floods ravaging Lousiana, this is a good time to reread Fire is a river that runs uphill.

One major reason that fire fighting in the western forests has become more expensive is the number of structures (homes) being built in the trees. One Colorado newspaper had the guts to run a story questioning if our firefighters should risk (or lose) their lives protecting the vacation homes of the rich after twelve firefighters died in the Storm King Mountain fire.
