looking for detailed past weather radar archives
I'm on the search for detailed radar archives dating back probably at least
10 years. I came across Weather Underground, which is the best I have been able to find so far, but I wish it was more detailed than just hourly, and I am seeking out possible alternatives. Any suggestions would be appreciated. Thank you. |

That is definitely a great resource. It took me a while to figure out how to decode the data, but I downloaded one of the recommended programs and I am viewing the various data now as actual past radar. I am just having a couple of issues. Since the data provided is so extensive, I am trying to narrow down the images that provide the best radar view, similar to Weather Underground: http://www.wunderground.com/radar/radblast.asp?ID=YUX It looks like Base Reflectivity 0.50° Elevation provides a good view. The only other issue is the radar residuals around the detection station. On the media maps often shown on TWC and others, they get rid of this- any idea how they do it? Thanks again! |

Ok, I think I figured it out after playing around with the software. Almost
all of the variables have filters so simply filtering the radar data to exclude the most sensitive (and noisy) range seems to get rid of the radar clutter. Now I just have to determine which is the highest resolution for the most zoomed in area. "Chris L Peterson" wrote in message ...

looking for detailed past weather radar archives
Perhaps you can help me out with something else too, Chris. First of all, I
am having a field day with all the data from NOAA site. Lots of specific data available at my fingertips! Couple of things I'm still looking for and maybe you can help me out: 1) Lightning data archives with the data presented on a map like the radar. Everything I've come across so far are paid services and I am obviously looking for something free. 2) Wind speed data also presented in a radar like format. They do it all the time for storms like hurricanes, but unless I'm mistaken, I don't see this anywhere on the NOAA site. Thanks in advance for any help! "Chris L Peterson" wrote in message ...

My use for various weather data is in my meteor research. Doppler radar sometimes catches the falling dust train from large fireballs. I also analyze the cold flight phase of meteorite falls, and for that I need to know the high altitude wind. That's available from radiosonde data- typically two balloon launches per day from a variety of sites. Historical data is online at http://www.esrl.noaa.gov/raobs/General_Information.html I don't generally care about surface data, but it can be useful sometimes when assessing witness reports, to determine where clouds might have been. There are useful historical weather maps (12-hour resolution) at http://weather.unisys.com/archive/index.php which might help you with your wind speed data. |

Hi Chris, This has sure been an interesting "journey" over the last several days and I have been led on various data paths. For near real-time and recently past lightning data, Weather Underground appears to offer a lightning option when looking at radar data: http://www.wunderground.com/radar/ra...ngeles%2c%20CA Under "Radar Controls". They do get their lightning data from an outside network. I've visited the website, but it doesn't mention archival data, so I don't know about availability. Still interesting to see current or past lightning data within the last hour though. The only resource I've come across offering lightning archives, plus a whole bunch of others, is Iowa state: http://mtarchive.geol.iastate.edu/ However, the major stumbling block so far is the way the data is stored. It's called GEMPAK and doesn't look like data decoding is available for Windows, although I am looking into it. |
