Last night at sunset we were just out from Boston when we launched the radiosonde. The pollution levels were up and we had to look through a haze to see the downtown skyline. A sea breeze began blowing cleaner air to us from the east. Late last night we headed east to meet up with a couple of the airplanes this morning. The goal was to have us and two of NOAA’s research planes all under a satellite which will be orbiting overhead. Pollution measurements could be made at many different levels of the atmosphere plus instrument comparisons could be made.
Of course it was foggy again. Wayne Angevine, a meteorologist back on shore was looking at live weather satellite images and got word to us that close by was a clear spot in the fog. The flight crew in the airplanes confirmed what Wayne said. When we got to the latitude and longitude they had directed us to, we found clear skies. The plan worked. The planes flew by making their measurements, several satellites passed over head, the ozonesonde was launched, all of the instruments on the Brown were continuing to collect data and Drew and I did Sunops.
Later today the rest of the fog burnt off, but there was still a haze as we slowly made our way back to the west. We need to be in the vicinity of Portsmouth so that we can meet up with the harbor pilot tomorrow morning. The pilot will direct the ship back into Portsmouth at about noon. The timing is actually important because we need to go in at high tide. Tonight the plan is to continue back and forth through the urban pollution. Before we get to port tomorrow, a couple of the crew will be diving under the ship to do some maintenance that should be interesting to watch.
Today is my last full day at sea on the BROWN. This next week I will be visiting some of the land based scientists, facilities and activities involved in NEAQS. We get into port about noon tomorrow.
I asked some of the scientist what is the one thing my students should know about this research project on air pollution. Some of the statements were:
We are studying a very complicated situation with no simple answers.
To study something very complicated takes lots of coordination and cooperation from numerous organizations and a lot of people.
Air pollution is a global problem not a local problem. Even people in areas, like Redmond, OR, with little pollution should be concerned. Air pollution doesn’t stay where it is made. North America gets pollution from Asia, Europe gets pollution from N. America, Asia gets pollution from Europe.
Each one of us needs to realize that we are part of the problem.
Question of the Day
How can you be part of the solution not just part of the air pollution problem?
