METAR Winds - True or Magnetic?

Is the wind magnetic or true in the METAR/TAF reports?

Huh?

Digital ATIS comes directly from ASOS which reports winds in true directions. There are 57 known sites where pilots are not getting magnetic winds. As of this writing, the FAA is not able to provide a complete list of these sites. According to Danny Mortensen (a flight crew training instructor for DHL and president of Airline Ground School), the sites listed below are digital ATIS sites.

ATL, DFW, MCI, PHL, SLC, AUS, DTW, MCO, PIT, SMF, BDL, EWR, MIA, RDU, TPA, BOS, IAD, MSP, SAT, CVG, IAH, MSY, SEA, DCA, JFK, ORD, SFO, DEN, LAX, PHL, SJC
