I am a chemistry major at a major university. In the future,
I would like to work in the air pollution field. What area of
study is better for a future career in air pollution and which
area did people working in NOAA study in college?
is the Air Resources Laboratory and what do you do?
Atmospheric Transport and Dispersion Modeling in General
research is being conducted on the long-range atmospheric transport
of pesticides in NOAA or other related organizations?
would like to know what kind of research is done concerning air
quality in New York City so far. Is there a permanent sampling
of air quality parameters? Where are these stations located?
previous aerosol studies have used 850 and 750 mb pressure levels
in back trajectory calculations. Why is this significant? Are
surface back trajectory calculations (at 1000 mb) more accurate,
due to presumably greater spatial resolution of meteorological
is the definition of the boundary (or mixed) layer?
there is a way to calculate or predict how far a certain organic
molecule will travel from an oil refinery on any given day? Are
there any models or sites out there that could answer that question?
want to use HYSPLIT to model both a Chlorine and an Ammonia spill.
We have looked all over the internet for the Henry's Actual and
Effective constants, as well as the surface reactivity and diffusivity
ratios for both Chlorine and Ammonia. Do you know where we can
find this information?
information is available on the CMAPF mapping function used by
many of your programs?
I have been
working with the C version of your emapf library and it has been of great use. I would like
to clarify a question about the conversion of grid points to lat/lon and vice versa
(in cxy2ll and cll2xy). When I use cxy2ll, are the lat/lons associated with the center of the grid box, the lower-left corner, or some other location?
way does the wind blow at the north pole?
you give me a brief history on the origins of latitude, longitude
and the division of degrees into minute and seconds. How old
is this system and who developed it?
is atmospheric humidity and how is it measured?
can I find a current emissions report on the greenhouse gases,
carbon dioxide, nitris oxide, and methane?
am a 7th Grade student and would like to know why is it always
cold in Antarctica?
information is available on how climate affects air quality and
is it, for example, that at 27 degrees C in both Calgary, Canada
and Osaka, Japan with a relative humidity of 60% one would barely
perceive any humidity in the air in Calgary and yet one would
feel very uncomforable and "wet" in Osaka?
Air Quality - Pollen - Atmospheric Chemistry - Acid Rain
are the major pollutants found in acid rain? How much acid (percentage
of total rain) would have to be present in rain for it to be
considered: low-acidity rain, medium-acidity rain, and high-acidity
rain; and what would be their respective pH levels?
you tell us the origin of the air that contributed to the rainfall
sample we measured on 12/15/99 in Front Royal, Virginia?
you offer a detailed answer on why/how the nitrogen deposition
from nitrate and ammonium is so high in the northeast states,
lower in the midwest states and very low in the west. What is
causing this atmospheric deposition condition?
son, a 7th grader, is working on a science fair project that
will hopefully show varying levels of acid rain in our county.
Is the HYSPLIT trajectory model the best way to show wind current
origins for rain falling on a given day, or is there another
way to show this? Also, can you recommend any other sites/sources
for middle school level research on acid rain effects, sources, detection, etc.?
much carbon dioxide is there in non-urban and indoor air?
much oxygen and carbon dioxide is there in the air we breath?
Does it change with the seasons? Does it change with the location
on our planet?
can lead be removed from the air, especially related to exhaust
gasses from internal combustion engines? Is there a chemical
process that can accomplish this instead of filtration?
anyone monitor the levels of carbon monoxide (CO) in the air
in Albuquerque, New Mexico? I need the data for my science fair
project. If that is not available, is there a way I can calculate
it through weather, etc. archives for the past month in Albuquerque
NM, and where would I find that data?
pollutants and how much are in the atmosphere?
can I find the latest research on aerosols?
you please provide me with Nitrogen Oxides content/index in the
atmosphere from year 1950 to year 2000? Please include the industrial
contribution numbers as well. Or could you please direct me to
another link to obtain the information?
there a Comprehensive directory or guide that would include all
organic or volatile organic chemicals and their compounds? Also,
where can I find the concentrations of gaseous organic and inorganic
substances in typical outdoor air. (April 2004)
Do you have any historical data or "rule of
thumb" information regarding the amount of salt (seasalt)
contained in the moisture in the air around coastal areas?
you have a database or maps for SO2 emissions in all the world?
cities do you suggest have the best air quality?
you have air quality information specific to a region other than
the Chesapeake Bay?
kind of impact does the air quality in the Kanawha Valley of
West Virginia have on my daughter and her asthma. I have the
option of moving west of Charleston about 30 miles, out of the
valley, and I wanted to see what kind of data there is to show
the differences in air quality between South Charleston, WV and
Milton, WV. Is there a way I can sample the air myself?
am looking for historical data on pollen and mold counts and
humidity data. Any information or websites you can direct me
to will be greatly appreciated.
there any plans in the future to have a segment that tracks pollen/air
particles on a daily basis for allergy sufferers?
