  Conventions: Please contact Prof. James Randerson (Email: jranders@uci.edu) or Dr. Mingquan Mu (mmu@uci.edu) for any question

  source_file: This product is generated from monthly ERA interim observations

  title: derived ERA interim

  Approach: I read the monthly 2m dewpoint temperature and 2m surface air temperature from original file, and calculated 2m relative humidity using the way by John Dutton (Ceaseless Wind, John Dutton. McGraw-Hill, 1976. pp 273-274). The final data were saved by each month and each year.

  Temporal resolution: monthly

  General information: This product was derived from ERA interim Dataset (1979-present).

  Spatial resolution: 0.5x0.5, 1x1 and 2.5x2.5 degree
