For many years, the front desk staff at FL2, CG1, and ML have provided banking services to employees. These services were provided as a convenience before ATM machines and online services were widely available. The campus front desk staff will no longer cash employee personal checks effective today, July 1, 2015.

With this change, UCAR would like to offer the sale of stamps at a 20% discount for a limited time at all locations. A list of stamps, the current inventory, and their sale prices is located at the link below.

The front desk staff will continue to offer workshop per diem check cashing for visitors and petty cash will continue to be processed until further notice. It is recommended that the check request form be sent to the finance department for cash reimbursements instead.

We appreciate your cooperation in helping us implement this cost-saving measure.

Speaker:  Michael Scheuerer
Date:       July 22, 2015    
Time:      3:30pm
Place:      FL 2 – Rm 1001
Title:       Statistical Post-Processing of GEFS Ensemble Forecasts
              for Precipitation Accumulations
Authors:  Michael Scheuerer and Thomas M. Hamill


We present and compare two different methods for statistical post-processing of ensemble precipitation forecasts which are developed and demonstrated with GEFS precipitation reforecasts over the conterminous United States and verified against an 1/8-degree climatology-calibrated precipitation analyses.

The first approach is non-parametric and forms, for each location, an new ensemble from the analyzed precipitation amounts by identifying dates in the past that had reforecasts similar to today’s forecast. A variant of this method is presented that augments the data at each location by finding supplemental locations with similar characteristics (climatology, terrain, etc.). The resulting increase of training data will be shown to be particularly beneficial for the probabilistic prediction of rare events.

As a second approach we consider a parametric method that generates full predictive probability distributions for precipitation accumulations by fitting shifted, left-censored gamma distributions to statistics of the raw ensemble forecasts. This distribution type is shown to be adequate for modeling the distribution of analyzed precipitation accumulations given the ensemble forecasts both in situations with good predictability (e.g. at short lead times) and decreased predictability (e.g. at longer lead times or during summer months).

Probabilistic forecasts by both methods will be verified using common metrics (skill, reliability, and so forth). We study how the different ensemble statistics and non-linear components in the parametric approach contribute to its performance, and we discuss, for both methods, the effect of training sample size on the reliability and resolution of the post-processed predictions.

Rollout of UCAR’s New Space Management System (Archibus)

Facilities Management, Safety & Sustainability (FMS&S) has been working diligently to rollout the new highly automated, web-based space management system, aimed at improving the accuracy, transparency, and efficiency of space allocation and reporting across all our buildings and organizations.  

In August (pending PC approval), we will launch a new interface to Archibus. This secure interface will allow admins to generate and export tabular reports and color highlighted floor layouts on demand.  It directly addresses the concerns of the UCAR Management Committee Working Group 4 (WG4) with regards to transparency of space allocation and assignment information, allowing admins to visually see and roll-up space for their organizations and sub-organizations based on UCAR's functional organization tree.  In the interface, admins will be able to hover over any space and readily see what the space type is, what division is assigned to the space and who is assigned to each office.  If an admin sees anything in question, they will be able to report it for immediate investigation and correction.

Move Requests – A New Streamlined Process

FMS&S will also be introducing a new streamlined process for move requests.  Last year, in response to feedback from the WG4, we introduced a new move request form and one-stop-coordination of move requests and moves.  Based on additional feedback from admins, we are refining that single form to provide admins an online selection from different types of moves, matching the move request form to the complexity of the move being requested.   The rollout of Archibus and UCAR’s move management process unfortunately means that we are eliminating the Space Planning Office and Project Manager position in FMS&S.

NCAR/UCAR Switchboard Function will end on 7/1/15

Currently when you dial 303-497-1000 or “0” during work hours, a switchboard operator answers the phone and directs your call. Judy Green has been the voice to help many of us for the past 38 years. Recently, Judy announced that she will retire on July 6. Judy’s retirement, along with diminishing use of the switchboard services, and alternative options including a phone tree (already in existence), directories via desk phones, People DB directory, and Google contacts, means  NETS will be discontinuing  the switchboard function on July 1. The phone tree will include access to UCAR SciEd/Tours, Security, Report an emergency, Communications, and Human Resources. CISL management and the President's Council have reviewed and endorsed this proposal.

The UCAR Community Art Program proudly presents two new exhibits:

Oils on Canvas by Betsy Cole

For Betsy Cole, art is continual discovery. First, there have been trips to Bali where she discovered that art can become a kind of play, a “dance of color.” Second, there is the energy of the earth itself – the scorching sun, deep cool lakes, and expansive forests all come alive vibrantly, almost mysteriously. But, for Betsy, the most significant discovery has been that art can heal. It brings light and joy to the darkness and pain. As she began to untangle her own life, viewing it as a journey, her love of bright colors acquired a new healing purpose. Cole's work will be on exhibit in the Community Art Gallery l of the National Center for Atmospheric Research Mesa Lab June 1, 2015 to July 31, 2015.

Contemporary Photography by Marc Bernardi

Marc Bernardi was born with a Camera in each hand and a curious mind. This anomaly has sent him rocketing on a lifetime of adventure and every imaginable type of photography. He is now fascinated with the abstract images that he creates from quite ordinary subjects that could be found on a walk. Then he transforms them into magical, colorful delights. He finds almost everybody who looks at them drawn in for a closer look, full of questions, and absolutely fascinated…Bernardi's's work will be on exhibit in the Community Art Gallery ll of the National Center for Atmospheric Research Mesa Lab June 1, 2015 to July 31, 2015.

August 11 - 14, 2015
NCAR Facility
3450 Mitchell Lane, Boulder, Colorado

GSI & EnKF - Starting Tuesday Morning on August 11 - 14, 2015
EnKF Only  -  Starting Thursday Afternoon on August 13 - 14, 2015
                  GSI knowledge is required for the EnKF Only Session

The combined Gridpoint Statistical Interpolation and Ensemble Kalman Filter (GSI/EnKF) Community Data Assimilation System Tutorial will be offered at the NCAR Foothills Laboratory, in Boulder, Colorado on August 11-14, 2015. This will be the sixth Community GSI tutorial, but the first time EnKF will be included.

GSI is the operational data assimilation (DA) system being used by various national operational and research centers, including NOAA and the National Aeronautics and Space Administration (NASA). It is traditionally a three-dimensional variational DA system and has been extended to run with advanced features, including the hybrid ensemble-variational data assimilation technique and the four dimensional EnVAR technique.

The EnKF system is a Monte-Carlo algorithm for data assimilation that uses an ensemble of short-term forecasts to estimate the background-error covariance in the Kalman Filter. The EnKF uses the observation operators in the GSI system to transform model variables to observed variables in observation space. Therefore, the types of observations available for use in the EnKF match those for the GSI. Currently this EnKF is running operationally as part of the GSI based hybrid data assimilation system for the National Centers for Environmental Prediction (NCEP) global applications.

The combined GSI/EnKF Community Tutorial will be held over the four days of August 11-14. The GSI/EnKF tutorial will consist of both lectures and hands-on practical exercises. The lecturers are invited from various GSI and EnKF development/support teams including NCEP/EMC, NASA/GMAO, NOAA/GSD, NCAR/MMM and DTC. The practical sessions will provide the necessary skills to run both the GSI and EnKF systems for both basic and advanced implementations. The tutorial will be tailored to the upcoming release code (GSI and EnKF) scheduled for June, 2015

The tutorial consists of a combination of classroom lectures and a hands on practical session. We offer a choice of two registration options:

    Full GSI/EnKF Tutorial (4 days): $400 (includes lunch and refreshments)
    EnKF Only Tutorial (1.5 days): $130 (includes lunch and refreshments)

There will be NO refunds for cancellations made on, or after 3 PM MT on Friday July 31th, 2015. Prior to the July 31th deadline, we will refund the registration fee, less $25.00 to cover administrative costs.

To register use the link to reg-on-line ( - More information can be found at the tutorial webpage (
