Photosynthetically active radiation (PAR) data from APEX Fen, 2005 - 2006

Photosynthetically active radiation (PAR) data from the all plots of a soil climate manipulation experiment in an Alaskan rich fen (APEX). APEX Fen is located in the Bonanza Creek LTER outside of Fairbanks, AK. APEX Fen uses a full-factorial water table (flooded or raised, lowered or drained, and control treatments, as well as a moisture gradient) by warming manipulation (warmed, unwarmed treatment). We predicted that successional changes in vegetation due to our experiment would change incident PAR levels at the soil surface.
