February 2009 Archives

Brief update:

  • Data from Point Sur (PTS) is now back online.  The problem was the satellite internet communication link; the satellite antenna became mis-aligned due to strong winds last weekend.  Today, the dish was re-aligned and the data started flowing again.

One significant update:

Data from the Point Sur (PTS) site stopped being communicated back to Boulder on the morning of 15 February.  It has been determined that the problem is related to a malfunction in the satellite internet connection; there does not appear to be a disruption in data collection.  PSD staff are troubleshooting the problem.  If necessary, a site visit is possible later this week.


HMT model status

We have fixed a significant bug in the postprocessing of the WRF-NMM member of the HMT ensemble, effective with the 18Z model run today.  You will probably note that the WRF-NMM precip amounts are much closer to the precipitation amounts from the other three.  You will also note that all four have quite a bit more precip than the HPC forecasts for the upcoming events.

Weekly teleconference:

| | Comments (0)
Quick reminder: due to the holiday on 16 February, there will not be a HMT-West 2009 status teleconference.  The next teleconference is scheduled for Monday 23 February at 1830 UTC.

One update:

  • Data from the Chico (CCO) site is intermittently not being communicated to Boulder due to a phone line problem.  PSD is working with the local phone company to address the problem.

A few updates:

  • As discussed on our call Monday 9 February, there have been several intermittent data outages throughout the network over the last few weeks.  Many of these are thought to be due to communication malfunctions in the data acquisition computers at those sites.   The "fleet" of computers used to acquire the data are relatively old and are due to be replaced over the summer.
  • Instrumentation at the Chowchilla (CCL) site is down due to a malfunction (i.e., not a communication problem); PSD staff will visit the site next week to repair.


Model outage info

The supplemental models provided via GSD stopped yesterday (Monday) with the 21Z cycle.  That's when maintenance work on the supercomputer began, and they're not done yet.  We did sneak in a 12Z cycle for today, and we've managed to move that by hand to the computer here in Boulder where it has to be for the HMT sites to get at it.  So those are there, and there's a chance we'll have the 21Z cycle for you later today.  We expect a return to routine ops after that.
