The North Central Lowland Plains |
|
| Since we wanted to
statistically derive a correlation matrix for each region, we needed at
least four sites to in the correlation. There is only one site within
the region based on the physiographic boundaries. Based on proximity, terrain, and precipitation, we choose
BLMO1, VOYA1 and GRRI1 to include in the correlation. IMPROVE and IMPROVE
protocol sites used in this analysis are shown in this
map. |
|
| The details of the
correlation analysis are provided in tabular format below. The
Representative Distance (Rep. Dist.) is 285 km for this region.
Representative distances were based from exponential curve fits to the
correlation verses
distance curves. |
