GPM Timothy 2008-02-11T09:40:07-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000017.html Here is a presentation I made on our research into the creation of a framework for the statistical analysis of large radar and lightning datasets, recently presented at the AMS annual meeting in New Orleans. Statistical Framework Presentation... Lightning Timothy 2008-01-28T10:32:24-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000016.html I created 3-D mosaics of radar data from 4 NEXRAD radars in Oklahoma, for analysis of a bow echo MCS that occurred on 20 June 2007. The mosaics cover a period of significant sprite production by the storm. These mosaics... Lightning Timothy 2007-11-13T14:30:18-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000015.html Here are some pictures I took during my recent trip to Taiwan. Of particular interest will be pictures from the survey of potential S-Pol sites, which you will find about halfway through the album. Pictures at KodakGallery.com... TiMREX Timothy 2007-11-13T11:37:53-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000014.html Here are blockage pattern simulation results for the two proposed TiMREX S-Pol sites, Air Force Academy and Levee. AFA has less blockage overall, but Levee has a nice view up the river valley. Both blockage patterns are much worse than... TiMREX Timothy 2007-11-12T16:43:19-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000013.html In TiMREX, S-Pol will likely scan RHI sectors on a regular basis. I tested the feasibility of using REORDER to grid RHI sector scans, similar to how we usually do with PPI sectors. The test was successful, with the RHI...

GPM Timothy 2007-11-12T15:35:25-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000009.html I am currently testing out Kdp calculation and thresholding with the NAME S-Pol radar data. Here is a nice example from the 05 August 2004 mesoscale convective system.... NAME Timothy 2004-11-16T11:56:23-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000008.html Here are some more daily summaries, similar to the last ones, but instead of plotting CG strike locations I plot the number of CGs of each polarity occurring during the allotted time period in 0.2 deg by 0.2 deg boxes.... STEPS Timothy 2004-08-04T16:46:32-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000007.html I have created GIF, PS, and PDF images of NEXRAD radar reflectivity factor and NLDN CG lightning strikes for nearly every day of June and July 2000. The files cover the 21-03 UTC (15-21 MDT) period, and feature maximum reflectivity... STEPS Timothy 2004-08-03T13:07:26-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000006.html I have completed the basic form of a program that loops through all 11 June 2000 MCS lightning data, as measured by the LMA, and compares these data to a simple convective/stratiform partitioning of the KGLD NEXRAD radar data. The... STEPS Timothy 2004-05-28T13:51:23-07:00 http://radarmet.atmos.colostate.edu/~tlang/archives/000005.html OK, the major updates to the website template are done. Minor ones may occur in the future, however. Now I can get on with posting my research!... General Timothy 2004-05-26T14:34:36-07:00
