This hot, dry October weather is spooky 👻 to some, but MAX is “fall”ing for it! We are out in Hartselle, AL for a local fall festival! We always love when we can work with our local communities!

Notice the haze the last few days? Us too! Our MIPS lidar Ceilometer data shows the Saharan dust that has intruded into the Tennessee Vally area this week.

The time-height section of Ceilometer backscatter data shows several features. The dust in the bright yellow/orange colors in the image indicates high backscattered signal return in the lower boundary layer.

Our teams were set up in N Texas today for the viewing of the solar eclipse! We were pleasantly surprised to have clouds dissipate over our sites which provided us with some amazing views and datasets!

Our Doppler lidar vertical data depicted building turbulence (blue=downward motion, red=upwards motion) throughout the morning which then was shut off during totality. Shortly after totality, turbulent vertical motions resumed.

Replying to @UAHuntsville
@UAHuntsville MAPNet staff and students have been prepping all week to for a @NSF funded solar eclipse research project! No matter the weather, teams will be operational in N TX to collect invaluable data throughout the day and interacting with the local communities.

On-site for the Ft Stewart prescribed burn to do micrometeorology fire science! Ignition from helicopters, then we scan the boundary layer wind flows and the smoke plume. Fire weather is severe weather!

A successful day of lidar coordination & data collection at Ft Stewart, GA ahead of prescribed burns tomorrow. Stay tuned for fire & smoke data as we collaborate with the US Forest Service, San Jose State, & other agencies/universities. Fire Weather is severe weather!!!

Who said we only study severe wx?? A few of our crew took off with our MoDLS (Mobile Doppler Lidar & Soundings) to Ft Stewart in GA this morning to document the boundary layer in and around wildland 🔥 while they host prescribed burns around the fort. More to come!

Notice the haze yesterday? You're not the only one! Looks like the smoke from the Canadian wildfires made their presence known over Huntsville yesterday. Our MIPS lidar ceilometer shows this smoke as it was transported into our area overnight Sunday into Monday.

Hurricane field deployments offer many challenges, but launching weather balloons in hurricane force winds is probably one of the more difficult, but rewarding tasks. These soundings and profiling data provides critical insight into hurricane and storm structure/evolution.

Hurricane season started on June 1. I sat down with researchers from @UAHuntsville today to talk about their research on the strength and rapid intensification of hurricanes. #HurricaneSeason #UAH #Research #Hurricanes

Just because we are in North Alabama doesn’t mean we can’t study hurricanes! Our students and scientists participate in many aspects of severe weather research, including hurricanes. A great piece highlighting tropical cyclone research taking place @UAHuntsville.

Here's my story on the hurricane research students at UAH are doing. They'll head to the Gulf Coast the next time a tropical cyclone threatens:

The @UAH @NSF MAPNet MOBILE INTEGRATED PROFILING SYSTEM (MIPS) ceilometer captured a high backscatter intensity yesterday morning, June 7th, indicating how dense the wildfire smoke was over North Alabama. Our rooftop camera also shows the dense layer of smoke.

Crew and platforms getting some much needed R & R after a busy few weeks with the @PERiLS_Project. Bring on the sunshine and 75° for the next few days ☀️ 🕶️ Definitely a good week for a car wash to get that Mississippi and Arkansas mud off! 🧼

Field work can be hard on instruments. Some slight modifications to our MAX radar pedestal and elevation motor repair should hopefully do the trick! Then, back on the road Tuesday for @PERiLS_Project IOP5! Phew.
