  Approach: I just read the data from the original data file and converted the latitude arrange from original 90N->90S to 90S->90N. The unit was convert from original 0.1 KgC/m2 to KgC/m2

  Temporal resolution: yearly

  General information: This product was derived from Northern Circumpolar Soil Carbon Database V2.2 (NCSCDv22) in top 1m.

  Spatial resolution: 0.5x0.5 degree
