Very nice meteorology course to go with our discussions on fronts and the Norwegian Cyclone Model.
Cloud atlas.


We are heavily into project development now. We have the new sensors for radiance and irradiance based on LEDs, hand held sun photometers, spectral sun tracking sun photometer, standard weather station, ultrasonic weather station, and downwelling IR measured by the FTIR spectrometer, in addition to data from the local UNR weather station on Valley Road.

We will begin FTIR spectroscopy theory and measurements as well. Simple intro, and presentation.

Week 13: 20 April - 24 April (Reno forecast tools.)

THURSDAY: MEASUREMENTS!!! WE START AT 5 a.m., and continue all day.
Remember, each student must get an FTIR spectrum and interpret it.
We will have: Ultrasonic anemometer, 2 weather stations from two students, irradiance prototype, 2 sunphotometers, tracking sunphotometer, and FTIR spectrometer.
We will search out the morning inversion with the FTIR, hope for some clear skies, and some cirrus skies.
Yay!

Stephen Bone gives a talk on ultrasonic wind detection. (Nice job Stephen). Then we prepare for measurements, and go through the sun photometer use.
We will check the operation of the automated sun photometer as well.

Given that we are having a frontal passage in the next 24 to 48 hours, we need an assignment to appreciate it. You can work together or in groups to evaluate the following:

1. Go to the www.wrcc.dri.edu/unr.html site and retrieve the data for wind speed, direction, RH, temperature, solar, and IR. Identify the frontal passage over the weather station. Discuss the variables that have changed and why as the front passes.

2. Get the bigger picture by satellite imagery and by surface analysis. Show the location of the low and it progression.

3. Discuss broadly with figures you get from google or your undergrad atms 117 book on the nature of the front, the vertical cross section, and the way it looks in space and time.

This must be done by Thursday. You can present one powerpoint presentation that gives all the details with each person taking a part. We will talk more about it in class tomorrow.
