Welcome to SEAC4RS

This post and its photos were provided by Tristan Hall, a student from Florida State University on the Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) airborne science mission.

I first arrived in Houston for SEAC4RS on Sunday, 18 August. My colleague Nick picked me up from the airport after a less-than-perfect landing. This was my second time arriving at Houston-Hobby, and 7th flight in two months; so naturally, I’m a pro. I took the stairs down to baggage and lugged my under-50 lbs baggage to go meet Nick at the pick-up area.

Nick drove me to the hotel which is basically an apartment; including a kitchen with all the necessary amenities, and a living room. He had to go back to his shift at Ellington; so I was left to let my imagination run wild on what to expect¬†tomorrow morning. Later my professor took me out for dinner, to my surprise, for all the work I’ve done back in Tallahassee. Thanks!

On Monday we took off bright and early for Ellington. When I arrived, I was in awe that I’m at a NASA-affiliated facility. The Meatball is everywhere; there are planes, barbed-wire fences, and guards. I have to go into an office to get my visitor badge – they forgot to sign me up for the “restricted sector” badge… again. ūüôā¬†¬†Oh well, I’ll make do. Off to the hanger where our command center is.

Being thrown into a shark tank doesn’t even come close to describe how I felt on day 1. Holy Toledo! 0-60 in 1.5 seconds. Everybody had already been in the swing of things for a couple weeks, by now, so I had to catch up fast! I had to look at the weather! Best Job Ever! Knowing how to forecast is more than just looking ahead – it’s looking behind, as well (that’s philosophical for ya there). I had been preoccupied in Tallahassee for the past couple weeks setting up a lab for ozonesonde measurements, so I had slacked a little on the whole “looking behind” aspect. In other words, I had no idea what the weather was like.

I spent all day trying to absorb everything. Every forecast model and how it compares to every other model. Every forecast discussion. Every historical satellite image I could find. Every variable of every model we have plotted on our FSU website and every other website out there (seriously, there are a plethora). Everybody here was on the same level as each other and knew what to expect of one another. I was overwhelmed. I felt underprepared, and I felt like I would never catch up.

This was a nowcasting shift, which is similar to forecasting, but only a couple hours in the future. The flight plan was pretty set, and conditions weren’t too nasty so it was an easy shift. I spent most of my time looking back, getting to know the weather. Dinner was soup and salad at the hotel lobby. Free is good.

Day 2 was a little better. On non-flight days we give a met briefing to lead off the science meeting. I got to see what to expect, and more importantly, what’s expected of me in the days to come. We report on current and future conditions, and point out specific regions of interest if they align with the science objectives of the campaign. Interests include convective outflow, smoke transport, and the North American Monsoon (NAM). After this, my time was spent understanding the atmosphere and its dynamic beauty. There is a trough in the east that just won’t go away, a cut-off low off the coast of California — with nothing steering it, a front moving down through the Great Lakes region, and nothing exciting over the Atlantic, to name a few. Dinner was “BBQ” provided by the hotel. It was chopped beef (not pork; or brisket!); however, it was sweet with a little too much liquid smoke. What’s with these Western folk? However, I had 2 buns, so I’m not really complaining. I do an excellent job of eating!

Day 3 – Wednesday – another nowcasting shift. I felt way more comfortable today. I was getting into the swing of things, and feeling more comfortable speaking up. The flight for today wanted to sample convection before it was intense. So, we had to find where convection was going to be and direct the planes to it. We settled on northern Alabama which had plenty of little popcorn cumulus. A view of the flight path could make you sick, it’s so swirly. Imagine a child drawing scribbles on a piece of paper. The pilots get in to the clouds and just go wild. The return path for one of the planes looked like it would intersect too strong convection; so it got really exciting for about an hour — and tense. People were depending on our radar skills. Once the planes made it past the bad convection, Nick and I displayed our GR2Analyst skills recreationally. Those non-met folks were amazed — cross sections; 3D plots; they kept coming back with new people in-tow asking us to show the 3D images. Dinner was stuffed peppers from the hotel! Not too shabby, again.

So far, I’ve seen an F-4, the 747 Space Shuttle Carrier, several NASA jets (which, for some reason nobody will let me drive. C’mon there are like 20 of them, let me take one out!), the DC-8 taxi, and the ER-2 take off and land, which has a chase car… Yup, a car that chases it as it lands, how do I get in that?!¬†¬†It has stabilizers on the back because it goes so fast!). I am learning fast, having a wonderful time meeting all these people, and having an EVEN MORE wonderful time forecasting and nowcasting. This is truly an experience of a lifetime. Thanks professor!
