ONLINE ASSIGNMENTS ARE GIVEN IN WEBCAMPUS.
TEAMS FOR HOMEWORK ASSIGNMENTS WHEN REQUIRED
T3 The Too Tired. (Bowman, Broc, Gabriela)
Those Guys (Robert, Daniel, Palina)
Baklava (Michael, Gina)
Isothermal (Joseph, Shuang, Hatef)
FC Spartak Moscow (Jacob, Kevin, Penelope)
Gliding High (Kylara, Jingting, Nathan)
Group 7 (Kaitlin, Ryan O.)
Homework 2. Students will turn in the assignment and present problems as assigned for their group.
Turn in problems through web campus.
Read chapter 3.
Do problem 3.18. (Groups will be assigned parts of this problem to present in class.)
Do problems 3.20, 3.23, 3.26 (also discussed in class), 3.28.
(it will be helpful to read problems 3.21 and 3.22 before doing 3.23).
Note: On problem 3.28, if the energy release, 5x106 J/m2 is from the latent heat released in the formation of a liquid water cloud,
the cloud might have properties as follows: 100 m thick, 600 cloud droplets per cm3, 20 micron cloud radius, liquid water path 2 kg/m2,
since the latent heat release from cloud droplet condensation is 2.5x106 Joules/kg. For those interested, here's a journal article on cloud properties.
(From this information it is possible to calculate the cloud optical depth, albedo, and transmission).
Problem 3.18 Presentation Assignments (each person presents at least one problem).
a, b, c (The Too Tired)
d, e, f (Those guys)
g, h, i (Baklava)
j, k, l (Isothermal)
m, n, o (FC)
p, q, r (Gliding High)
s, t (Group 7)
u, v, w (Group 8)
Homework 1. Turn in this homework assignment through webCampus, using Microsoft Word.
Read chapter 1.
A. Do problem 1.6. Write your answers into the first part of the MSword document you will be turning in for this assignment.
B. Do problem 1.12. Go to the South Pole and find a sounding that has a temperature structure like this. Include the SkewT LogP graph in your report.
C. Write a short report for the following analysis.
Calculate a time series of the average mass per unit area (units of kg / m2) of the air between UNR and DRI for the month of January 2018, and between DRI and Slide Mountain for the month of July 2018.
Calculate a time series of the lapse rate (-dT/dz) between these stations as well and overlay with the first graph.
You will have a total of 2 graphs, one for each month.
Discuss the variation of the average mass per unit area, and its relationship, if any, with the lapse rate, or other variables you might explore.
We will develop some theory in class for this problem.
The time series for the sites need to be synchronized, to take into account any missing data.
The UNR pressure sensor is not properly temperature compensated.
Here's what we use to compensate it for temperature variation.

NOTE: A short report should be written like a short section in a text book.
A. Title for the report. Your name.
B. First paragraph describes what's in the report, describes what is to be accomlished.
C. Provide figures, each figure with a number and caption. Figures must be in publication format -- high quality figures with 16 point (or greater) bold black font; tick marks inside. All axes 1 point thick and black.
D. Each figure must be discussed in the text by number, describing the significance of the figure and its relationship to other figures as needed.
E. Any equations should be offset, as in a textbook, and each equation should have a number. Refer to equations by number.
F. The last paragraph should summarize the overall outcome of the report.
Get started early.
Take advantage of the UNR writing center to have them read your report draft to give you feedback on writing quality.
A. Meteorological data can be obtained from the University of Wyoming web site.
B. Most (or all) computers readily accessible to all students, using their netID, have Google Earth, MSword, and Excel.
C. You can use your netID to also access these software packages through the UNR remote services application.
FINAL PROJECT, START NOW!
Atmospheric Physics students take photographs of the atmosphere or environment, and explain the Atmospheric Physics connection.
For example, blue sky, sky polarization, coronas, halos, rainbows, lenticular clouds, gravity waves, lightning, water phase clouds, ice phase clouds,
inferring air motions and winds from cloud structures, contrails, vortices in contrails, sky color during pollution events, sky color near the horizon, sky color at sunset looking to the east.
Photographs of the dendritic nature of ice growing on windshields on cold days, the shape and nature of icicles, dew on a moist mornings are also possible topics.
Photographs of snow flakes and snow crystals, here's a discussion.
If you have special hobbies or work, like paragliding, Atmospheric Physics related aspects can be included in your project.
You can use soundings, satellite images, etc, to also help tell the story.
ATMS 411 students will do a presentation
ATMS 611 students will do a presentation and a report.
Due date will be in the last week of school.
Resources that may help
Gravity wave discussion.
Snow crystal/flake observations.
NASA WorldView for satellite imagery. You can add layers for additional information.
National Weather Service balloon soundings, served by the Univ of Wyoming.
