Normalization of dBz Observations Across Day-Side Stations for Correlation Analysis

This study focuses on the normalization of dBz measurements by the factor |dB| and B0, where B0 is calculated as the square root of the sum of squares of magnetic field components (Bx, By, Bz) with B0 set at 5 nT for estimated data. We analyze results from day-side observation stations to check for good correlation events, defined as events with correlation coefficients greater than 0.5 for either dBz or normalized dBz. This exploration accounts for missing estimated data and addresses the impact of available station data on the analyses.

Presentation Transcript

  1. Use stations looking at day side • Change normalization factor dBz/|dB| -> dBz/B0 for observed data, B0=(Bx^2+By^2+Bz^2)^0.5 for estimated data, B0=5nT

  2. For both method, check 5 good correlation events (coefficient > 0.5 for either dBzor normalized dBz) and see how it changes

  3. all stations day side stations Estimated data is missing Not enough station available
