Correlation Between Wind Direction and Observed BrO concentrations

Objectives and hypothesis
Objectives and Hypothesis

  • Hypothesis:

  • Wind direction and BrOconcentrations (pptv) are correlated.

  • Objectives:

  • Using regression fitting, bootstrap method, and correlation coefficient test the hypothesis above.


Data acquisition
Data Acquisition

  • Data used was collected during the 2010 Greenland field mission using a Chemical Ionization Mass Spectrometer

  • Data collected from 26 May 10 to 20 Jun 10.

  • Location: Summit Station Greenland (72°35'46.4"N 38°25'19.1"W)





Conclusions
Conclusions

  • BrO concentrations have small correlation due to low correlation coefficient value (0.1539)

  • Bootstrap method confirmed correlation coefficient

  • Average wind direction: 192 deg. (S)

  • Best correlation regression—Least Squares method.
