NCEP Constituent Workshop

The National Centers for Environmental Prediction (NCEP) held a constituent workshop on April 14, 1998. The presenters' slides and handouts are accessible at the Environmental Modeling Center's home page <>. This home page also contains excellent reference material on various model output including an FAQ on the model and a nearly completed comprehensive documentation of the MRF.

ASOS Update

The 532nd Automated Surface Observing System (ASOS) was commissioned on April 29, 1998 at the Baltimore Science Center in downtown Baltimore. This ground level observation site (KDMH) will replace the Baltimore Custom House which was a rooftop observation station.

Useful information on the ASOS program including a users guide, product improvement activities and implementation status can be found on the ASOS home page at

SAMEX 98 Experiment

One of the most critical and highly debated topics in numerical weather prediction today concerns the data requirements, analysis and assimilation strategies, and spatial resolution and physics parameterizations needed to accurately predict the initiation, evolution and decay of intense mesoscale weather systems. An initial multi-institutional experiment has begun to examine the significant issues involved with the short range prediction of intense weather systems. The Storm and Mesoscale Ensemble Experiment (SAMEX) will run from May 1, 1998 through May 31, 1998. Model output from the experiment is available on the web at <

GOES COMET Training Modules

"Radiative Transfer" and "Meteorological Sounders" COMET (Cooperative Program for Operational Meteorology Education and Training) modules have been updated and are available on the web. The updates include more satellite examples in the radiative transfer section, more product and radiance animation and a summary of the GOES 10 sounder in the meteorological sounders section. You can locate these modules at

Other GOES News

Demonstration of temporal and spectral resolution from the GOES 8 sounder is on the web. All 19 bands of the GOES 8 sounder are displayed for April 6 and 7 1998. The loop clearly shows the information content of the sounder bands. The color-enhanced loop and one still image can be accessed at <

GOES 10 sounder analysis has been completed. The noise on the GOES 10 sounder channel has been found to meet specifications for the fist time in the current series of GOES sounders.

EOS Launch Delay

The Earth Observing System (EOS) AM-1 spacecraft's launch will likely be delayed from late June 1998 to at least the end of the year. NASA has found software performance problems with the ground system software required to control, monitor and schedule science activities on the eentire series of EOS spacecraft. EOS AM-1 is part of NASA's Earth Science research program to study the earth's land, oceans, atmosphere, ice and life as a totally integrated system.

Satellite Convergence Update

In April, NOAA assumed prime support for the second operational Defense Meteorological Satellite Program (DMSP) satellite. The National Environmental Satellite Data and Information Center (NESDIS) satellite operations control center is now the prime control site for all U.S. meteorological satellites.

RUC 2 Model

The Rapid Update Cycle-2 began running operationally at NCEP on April 6, 1998. A bulletin board forum with RUC-2 questions and answers and information on real time runs as well as the RUC 2 Technical Procedures Bulletin can be accessed at the NOAA Forecast Systems Lab home page <>. This web site also provides access to 40 km RUC-2 real time plots.
