Table of amplitudes #19

Open cahartin opened 6 years ago

cahartin commented 6 years ago

for each variable model | basin | hist ampl | future ampl

cahartin commented 6 years ago

and a table of percent difference or percent decadal trend model | basin | absolute change (that would just be the difference from 1st table - maybe redundant) | trend min | trend max

@cahartin now the second set of tables values are the percent change in the labnotebook_tables (2).zip decadal slope

kdorheim commented 6 years ago

@cahartin okay so now I only have one set of tables that contains the percent change in the mean amplitude, min, and max for each variable / basin / model + multi model mean.

Consolidated percent change tables where the largest and smallest percent CMIP reflects the magnitude of the percent change .

So one problem with this table is that is that it sometimes fails to capture the spread of the CMIP models are increasing in percentage and decreasing in percentage just the magnitude of the percent change.

If we are interested in capturing the full spread, both direction (increase and decrease) as well as magnitude we may want to visualize this information in a box plot....

kdorheim commented 6 years ago

An alternative to presenting the percent change information in a table is a boxplot that illustrates the CMIP spread in the magnitude of the percent change and the direction. This really only applies to pH where models are inconsistent if the seasonal stat increases or decreases in the future.

Those look cool. thanks for thinking of that!
