error in Makiranta_2012_tiol #239

Krista & Ben, 

 

With Krista we have emailed a lot a few years ago and with Ben related to the Palviainen et al. paper from last year as we were both coauthors.

 

Thanks for the great work in expanding ForC-database and congratulations for the two recent papers, in Environmental Research Letters and Global Change Biology which we have read very carefully.

 

We, together with postdoc Xia Chen, are starting to model succession from physiological principles based on ForC. I noticed that a datapoint in Finland that I checked had a very high biomass value:

x | y | Forest.type | Stand.age.years. | AGB.t.ha. | Reference -- | -- | -- | -- | -- | -- 25.11667 | 61.36667 | Natural | 55 | 281.702128 | Makiranta_2012_tiol

I checked from the original publication and even asked one of the authors and we do not understand from where the value of 281 Mg/ha comes from. 

 

Is there another way to report suspicious data values in ForC or is this the way? This is just one row of data but I am afraid that e.g. some rows have jumped and several rows are now having wrong values so it could be wise to trace the source of this potential error. Xia checked and Ben's name was mentioned as the one entering the data.

 

Regards,
Markku

I flagged the value as suspicious so that it won’t get used in future analyses, and will review when I have a chance.

@bpbond , flagging you here FYI.

This value itself was correct, but value is total biomass (aboveground and belowground), and units are dry organic matter, not C.
