HMT-West 2009: Project Status

HMT ALPS Server down Tuesday (4/14) for upgrade

Mon, 13 Apr 2009 16:22:56 +0000

HMT ALPS Server will be down Tuesday (4/14) for upgrade to OB9.0

HMT Models/Server back up

Fri, 03 Apr 2009 20:53:33 +0000

The HMT Models and server are back up. Please let me know if there are any problems.

No HMT Model data available 3/30 thru ~ 4/01

Fri, 27 Mar 2009 17:31:01 +0000

We will be replacing the FSLC NAS on Monday morning (3/30/09). This work requires that all cluster packages be shutdown and all users log off of the workstations and servers. The NFS mounts to the existing NAS must be removed so all processes relying on those NFS partitions must be stopped.

FSLC will be unavailable from 6:00 AM Monday morning (3/30/09) until 5:00 PM Wednesday (4/1/09). No HMT model data will be available until after the system is back up. We will update the blog when this occurs.

model runs

Wed, 11 Mar 2009 19:05:50 +0000

Yesterday and today most of the model runs were lost due to problems with super computer. The problems are hopefully resolved. We will pay close attention.....

NMM boundary conditions using NAM out to 72 hrs

Thu, 05 Mar 2009 16:43:40 +0000

The NMM ensemble member is now using the NAM for the lateral boundary conditions. The NMM model runs out to 72hrs.. The other three ensemble members are still using the GFS and run out to 120hrs.. All four members are used for generating ensemble mean fields.

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

Fri, 13 Feb 2009 19:37:27 +0000

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:

Fri, 13 Feb 2009 16:47:47 +0000

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.

Instrument Status: 11 February 2009

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

Tue, 03 Feb 2009 20:27:01 +0000

Folks,

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.

Mean QPF fields are again available on ALPS workstations

Wed, 28 Jan 2009 19:15:37 +0000

The mean QPF fields are again available. To access them through the D2D volume browser, first select the regional scale:

Source: Local > locEnsHMT

Fields: SFC/2D > Precipitation

                               > Precip > Precip Accum
                               > HMT Ensembles > POP
                               > HMT Ensembles > Precip Mean > 6 Accum., 12 Accum, ...

A few things to report:

The data communication problem from Cazadero (CZD) has been resolved (as of 22 January)
The wind profiler at Point Sur (PTS) has been repaired (as of 22 January).
The ETI precipitation gauge at Huysink (HYS) has been repaired (as of 21 January).
Surface meteorology data at Big Bend (BBD) is not available due to a datalogger power problem. It is suspected that one of the surface meteorology instruments is draining the battery excessively. PSD staff are investigating.

HMT Models back up today (Friday 1/23) but no Ens precip. means

Thu, 22 Jan 2009 23:11:11 +0000

The models appear to be back up and running but the ensemble mean precip. fields are old. Will check with the modeling folks and let you know when they are back up.
