- variable: BURDENDUST [kg/m2]
- Dust aerosol burden — total concentration of dust per meter square over a grid
- Dust aerosol burden — total concentration of dust per meter square over a grid
- (High / Low): the months when the amount of dust is over / under 2 times standard deviation
Examining Correlation between Dust Indices & Precipitation: I do not calculate it in the whole time series. I only calculate their correlation in the months when the dust index is high or low. (ex: If there are 48 months when index1 is high, I calculate the correlation between dust index1 & precipitation in those 48 months)
(1) Index 1: (50-90E; 20-50N)
(2) Index 2: (100-80W; 30-45N)
(3) Index 3: (75-55W; 15-45S)
- The correlation maps are not consistent with composite precipitation patterns for each index
- Most of correlation maps are not statistically significant:
- Composite precipitation patterns tell us that the modified dust emission might be critical to the resulting precipitation.
- However, the correlation maps suggest that the dust may not directly related to the precipitation.
- Or, the dust concentration is partially modulated by precipitation
