Dendrochronology Lab

EAS 104 Lab, Perspectives of Global Warming Lab

Lab 1 - Dendrochronology Study

Task 2

Find the precipitation (in millimeters per day) for the year you have selected, for each Tree Ring, in Part I and enter the information below. (10 points)

Example:

Tree Ring 1- Jackson Mississippi (Lat: 32.299N, Lon: 90.185W)

Year: (same year that you chose as below average precipitation in Task 1)

NASA Satellite Precipitation Plot - Jackson Mississippi

Precipitation for year selected: # (mm/day)

Q1. Did the satellite data confirm your tree ring analysis for each location? Describe yes or no. If not, what might account for the differences between the two measurements? (2 points)

Q2. Can you suggest data sets for other parameters that you could check that might support either the tree ring or the satellite data, if they do not agree? (2 points)

Q3. Which of your data (tree ring analysis or the satellite data) best reflects year-long changes in precipitation? Explain your answer in terms of your data. (2 points)
