Balloon reports 00Z NAM RAOB RECAP...
Twice a day, NWS and partner agencies release weather balloons that carry a radiosonde — a small instrument package that radios back temperature, humidity, pressure and wind as it climbs. Those soundings are one of the main ingredients in a forecast model’s starting conditions. This section is the roll call of stations that had a problem for the 00Z run of the NAM.
18 stations were flagged: 7 sent no usable sounding at all, 9 reported a numeric status code, 1 had a balloon burst early, 1 had bad data removed by quality control. A handful of gaps is normal and is not by itself a sign of a forecast problem — the models are built to work with an incomplete picture.
| Station | Where | What happened | As printed |
|---|---|---|---|
| OTZ 70133 | Kotzebue, Ralph Wien, AK | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| BET 70219 | Bethel/Bethel Airport, AK | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| SNP 70308 | St. Paul Islands, AK | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| AKN 70326 | King Salmon, AK | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| TWC 72274 | Tucson, AZ | The station reported status code 10159. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10159 | 10159 |
| FWD 72249 | Fort Worth, TX | The station reported status code 10148. NWS does not publish a public legend for these codes, so we will not guess at what it means — it signals some problem with the launch or the data. unrecognised status code 10148 | 10148 |
| OME 70200 | Nome, AK | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| BRO 72250 | Brownsville/Intl, TX | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| GCM 78384 | Owen Roberts Airport Grand Cay · Cayman Islands | Ground equipment failure — the station’s tracking/receiving equipment was down, so no usable sounding was produced. | 10142 |
| ACA 76805 | Acapulco, Mexico · Mexico | The balloon burst early. It stopped reporting at 688 mb, so this sounding only covers the lower part of the atmosphere — forecasters and models got no data above roughly 3.1 km (10,500 ft). (688 mb ≈ 3.1 km (10,500 ft)) | Short to 688 mb; purged temps/moisture at 694 mb...super-adiabatic lapse rate |
| REV 72489 | Reno, NV | Quality control removed part of this sounding before it reached the models: temps/moisture 470-467 mb...super-adiabatic lapse rate. The rest of the sounding was still used. | Purged temps/moisture 470-467 mb...super-adiabatic lapse rate |
| ADQ 70350 | Kodiak, AK | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
| SYA 70414 | Shemya AFB, AK | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
| JAX 72206 | Jacksonville/Intl, FL | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
| NKX 72293 | San Diego/Miramar, NAS, CA | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
| VEF 72388 | Las Vegas, NV | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
| GRB 72645 | Green Bay/A.-Straubel, WI | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
| OTX 72786 | Spokane, WA | No weather balloon data from this station reached the model for this cycle — either no launch happened or the data did not arrive in time. | No report |
