Dear FIREXers;Today we had our first two room burns! After a slow start because of the elevator being stuck and other small issues, we managed to get two burns in. There seemed to have been only few minor issues during the fire, so we should call this a successful start to the second half of… Read More

Dear FIREXers;The transition from stack burns to room burns is almost finished! All the instruments are in its new (or old) location and most are up and running. Thanks to everybody for making this move work so smooth and for helping your colleagues so graciously. This means we are ready for our first room burn… Read More

Dear FIREXers; We had 5 good burns with Lodgepole as the big burn. The lodgepole was pretty wet and produced a lot of smoke and glowing branches, so this was pretty unusual for us. We also repeated the Excelsior and had new fuels beargrass and Jeffrey pine bark. Two more days of Stack burns until… Read More

Dear FIREXers; We had 5 good burns: Sub-alpine Fir from Fish Lake, Douglas Fir for the big burn, Lodgepole Pine, Ponderosa Pine, and Rice Straw. The afternoon presentations were give by Ale Franchin (AMS) and Matt Coggon (The Oxidation Flow Reactor formerly known as PAM). We are looking to wrap up Stack burns this Saturday and envision… Read More

Dear FIREXers; Today the large fire was Engelmann Spruce, which we had to repeat in the afternoon for a second try at filling the chamber properly. It seemed to work on the second go-round. Tomorrow we will have Douglas Fir as the big burn, rice straw, ponderosa, lodgepole and duff for the smaller burns. We are… Read More

Dear FIREXers; We made it to Fire050 today and we marked the special occasion with some very interesting burns today! The big fire was the FASMEE fuel Subalpine Fir from Fish Lake. In the afternoon we had a burn of excelsior, which is a very high cellulose fuel with very low nitrogen content, and then… Read More

We had another successful day of burns, involving another round through the western fuels, Ponderosa pine, Douglas-fir (it’s not really a Fir we have been told), and Engelmann Spruce (which is actually a spruce). We tried a short burn for calibration purposes, but will have to take a Mulligan on that since key instruments didn’t… Read More

UPDATE We had an eventful day at the Fire Lab on Friday. The first burn had to be canceled due to a problem with the elevator, which is now fixed. The remaining burns revisited Ponderosa Pine (full, litter, canopy) and a burn of Douglas Fir. We had science presentations from Kanako Sekimoto (H3O+ ToF peak… Read More

Dear FIREXers: Today we had three successful burns of chaparral, one Loblolly Pine (southeast fuel) and one duff. Today’s science presentations were about the chamber from Abril, Ben, Ed and Rob. Thanks for the great discussion! TENTATIVE Plan for the upcoming days: 10/14 – 9 AM start for 5 burns: Ponderosa Pine realistic (big burn), litter, canopy and Engleman… Read More
