Staff Notes Daily Announcements

Are your ready for the purchase order processing downtime (June 5-16) before UProcure Go Live on Monday, June 19? During these two weeks we will be migrating and testing data in IFAS and UProcure. Contracts and Accounts Payable will not encumber any new purchases orders or funded contracts, or make payments against existing purchase orders between Monday, June 5 and Friday, June 16.

Be sure to take these next steps:

  • Before close of business, Wednesday, May 31: Submit your requisitions and invoices against current purchase orders for processing.

  • Beginning Thursday, June 1:

    • For requisitions: Wait to enter your orders into UProcure beginning Monday, June 19.

    • For invoices: Continue to send your invoices to Accounts Payable.  They will start payment processing again on June 19. 

If you have a purchasing emergency during the downtime period, contact your Contract Administrator.  If you have an invoice emergency, contact Karen Jess at ext. 2138. Thank you for your cooperation and patience.

Stay tuned to Staff Notes and the UProcure Purchasing Project web site  for the latest updates!

Spatial Methods That Combine Ideas From Wavelets and Lattices: LatticeKrig
Doug Nychka
National Center for Atmospheric Research

Kriging is a non-parametric regression method used in geostatistics for estimating curves and surfaces and forms the core of most statistical methods for spatial data. In climate science these methods are very useful for estimating how climate varies over a geographic region when the observational data is sparse or the computer model runs are limited. A statistical challenge is to implement spatial methods for large sample sizes, a common feature of many geophysical problems.  Here a family of covariance models is proposed that expands the field in a set of basis functions and places a Gaussian Markov random field (GMRF) latent model on the basis coefficients. The idea, in contrast to fixed rank Kriging, is to use many basis functions organized on lattices. In addition, the basis functions add more smoothness and larger scale spatial dependence than a GMRF alone.

Title: Aerosol-Cloud-Radiation Interactions in the Arctic: Imprtance of the ice nucleating particles (INP)

Abstract: Cloud microstructure is strongly linked to the aerosols and their ability to nucleate liquid water (CCN) or ice (INP). Cloud phase is mostly determined by the aerosol thermodynamic properties. It is therefore important to understand these aerosol-cloud interactions since they determine cloud phase and cloud radiative forcing. In this talk, I will first give a brief overview of the aerosol indirect radiative effects and then focus on the INP deactivation effect within ice clouds and its effect on clouds and radiation. Simulations and observations of the deactivation effect during the ISDAC Campaign in April 2008 will be presented. Results show the importance of the INP parameterization used in models and the need to consider the chemical composition of the aerosols. In a second modelling study, the Weather and Research Forecasting Model coupled with chemistry (WRF-CHEM) is used to simulate the INP concentration observed during the NETCARE field experiment that took place over the Canadian Arctic near Baffin Island in July 2014. WRF-CHEM simulates several gases and particle matters relevant for ice nucleation. Using this information combined to parameterizations based on field and laboratory studies, it is shown that the model simulates within a factor 5 to 30 the observed INP concentration depending on the ice nucleation parameterization used. Results suggest that large particles are the main contributor to the INP concentration suggesting that a bin scheme for the simulation of the aerosol size distribution is needed to get more realistic INP values.

NCAR|UCAR colleagues were saddened to hear news of the death of Med Medrud on April 18 at the age of 92. He retired from NCAR in 1989 after more than 20 years as a meteorologist and manager, first in the Atmospheric Technology Division (now EOL) and later in the Atmospheric Chemistry Division (now ACOM). In a note with news of his passing, retired NCAR staff member Teresa Rivas recalled that Med "always had a smile and a kind word for everyone."

A memorial service of worship will be held Saturday June 3, at 1:00pm at the Boulder Friends Meetinghouse, with a simple reception to follow. An obituary has been posted on the Daily Camera's website.

Observations and modeling of the atmospheric boundary layer and
its impact on the general circulation
Gunilla Svensson, Stockholm University

The atmospheric boundary layer is the turbulent layer that is in contact with the surface and where the exchange of heat and momentum by turbulent processes occur. Turbulence is a small-scale process that are not resolved in numerical models used for weather prediction and climate projections and therefore has to be parameterized. Some evaluation of boundary-layer properties and surface fluxes will be presented. The focus will be on the link between the momentum transfer at the surface and its effects on the general circulation.

The effect of the boundary-layer friction on large-scale circulation can be expressed in terms of the cross-isobaric flow angle, related to the surface stress acting on the flow. Analysis of this angle reveals that it is systematically underestimated in climate models and reanalysis products. An idealized single-column model framework and LES results are used to examine the turning angle over a range of geostrophic winds and static stabilities. It is found that both the vertical resolution and the stability functions, e.g. the so-called long- and short-tail formulation in stably stratified conditions, impact the cross-isobaric angle.

After the UCAR/NCAR/UCP Education Summit, multiple people inquired about the next steps we could take with Virtual and Augmented Reality within UCAR/NCAR/UCP.  

To understand the next steps, we have decided to get together some brainstorming groups to help us understand what is available at UCAR/NCAR/UCP, what is out there that we could investigate, and how we could take advantage of these technologies in data visualization and education.  Initially, these brainstorming sessions will be separated into two groupings, one for the technical side and the other for the users (data providers/educators).  We have started two different Doodle polls to figure out the timing for the first meetings.  Both meetings are meant to occur during the first two full weeks of June.  

For those interested in the technical side, please RSVP here: https://beta.doodle.com/poll/zxyq6aw8qrtgkz6m

For those interested in the user side, please RSVP here: https://beta.doodle.com/poll/r3wm2kqimcxxecr3

Hope to see you there to share and understand the possibilities.
