Data from the Sheldon Point Airport station can help with
aircraft, marine, and land transportation. By studying the
weather in Nunam Iqua and how it varies from the surrounding
stations, a better understanding can be gained of how to forecast
changes. Some of the questions below provide problems students
at Nunam Iqua can work on. Data can be downloaded from the
historical section and used to work on mathematics and statistics
problems. Contact Michael
Lilly for questions on teacher applications for the ADOT&PF
weather station data.
Between 11/1/2003 and 11/15/2003 a flooding event occurred.
Graphs of the wind speed and direction collected during this
time period have been provided and can be viewed by clicking
on the appropriate links below. A wind speed and direction
reading is taken every 5-seconds, beginning at the top of
the hour. The Instantaneous data is the actual value taken
at the top of the hour over a period the two week period.
The hourly averages are the 5-second values averaged over
a one hour period, beginning at the top of the hour.

vary?
