Decoding Cooperative Observer Reports ( WxCoder and IV-ROCS) Example 1. Most Common:   ABFN5 0212  M DH1700/AD 05/PP 0.10/SD T/SF 1.0/TA 35/TN 28/TX 38 ABFN5 = Station ID (e.g. Albuquerque Foothills) 0210 = Observation Date (e.g. February 10) M =Time Zone (e.g. Mountain) DH1700 = Time of Observation (e.g. 1700 hrs or 5pm LST) AD = Climate division PP = 24-hour precipitation (e.g. 0.10 inches) SD = Snow depth in inches (e.g. Trace) SF = Snowfall in inches (e.g. 1.0 inches) TA = temperature at observation (e.g. 35 degrees F) TN = minimum temperature (e.g. 28 degrees F) TX = maximum temperature (e.g. 38 degrees F) Example 2. Observation with wind and humidity: SELN5 1011 M DH0700/AD 02/PP T/PT 1/SD 0/SF 0.0/TA 45/TN 42/TX 70 .A1 UD 203/UP 24/UR 350/US 7/XRIRZN 18/XRIRZX 69 Codes same as in example 1, except: UD 203 = Direction of peak wind (e.g. 203 degrees or Southwest) UP 24 = Peak wind speed in mph (e.g. 24 mph) UR 350 = Wind direction  at observation time (e.g. 350 degrees or North) US 7 = Wind speed at observation time. Either 0 or 7 mph. XRIRZN 18 = Minimum RH last 24 hours (e.g. 18 percent) XRIRZX 69 = Maximum RH last 24 hours (e.g. 69 percent) Other weather codes that may be encountered: EP 0.14 = Evaporation (e.g. 0.14 inches) TBIRZN 4.062 = Minimum soil temperature at 4 inches depth in last 24 hours (e.g. 62 degrees F) TBIRZX 4.080 =  Maximum soil temperature at 4 inches depth in last 24 hours (e.g. 80 degrees F) TPIRZN 45 = Minimum water temperature last 24 hours (e.g. 45 degrees) TPIRZX 82 = Maximum water temperature last 24 hours (e.g. 82 degrees) PPK 0.28 = Precipitation since last observation (e.g. 0.28 inches); Used in special observations SFK 2.0  = Snowfall since last observation (e.g. 2.0 inches); Used in special observations
