issue in delta-delta values in ISRaD_extra #126

Closed aahoyt closed 5 years ago

aahoyt commented 5 years ago

Some of these really make no sense based on the other data in the template. I have not been able to figure out where the issue is arising, since the dates, fraction modern & 14c values all look ok. Further exploration is needed to resolve this so we are not serving up faulty calculations in ISRaD_extra.

Examples with problematic values: Gaudinski_2001 Sierra_2012 trumbore_inc_unpublished

I'll take a stab at this today.

@aahoyt Can you explain the exact issue a bit more? I'm still struggling to find anything erroneous in the calculations, but out of context it's hard to see what the problem is.

If I remember correctly, you were seeing incubation dd14c values that were too low---is that correct?

aahoyt commented 5 years ago

The values were all over the place. Just sent you the scripts/plots.

aahoyt commented 5 years ago

Reminder - this has never been corrected. We should fix this bug or remove it from ISRaD_extra before submitting the manuscript

I'll also email an alternative atmospheric record file from Graven et al that Sue suggested to avoid the forward projection issue in SoilR

aahoyt commented 5 years ago

I think this was likely due to the date fill issue so I'm closing this issue and starting a more general delta-delta update issue.
