1/72 Hasegawa kit. I first meant to paint it in Jv 44 colors, but then found out I didn't have any red, so I made up some markings. Still playing with my camera and the levels feature on gimp.

Edited visualization from the HRRR-Smoke model of where smoke from fires in Northern California were predicted to go.

Original caption: By the time the U.S. Forest Service declared the Mendocino Complex Fire 100 percent contained in mid-September 2018, it had burned for nearly two months, destroyed 157 homes, and scorched more than 459,000 acres, making it the largest wildfire in California history. Wildfires in the state burned more than 1.3 million acres from January 1 through November 4, shrouding the region and, at times, whole swaths of the country, in smoke.
In the past, the behavior of such wildfires and their smoke plumes was notoriously difficult to forecast. “It was a challenge for the atmospheric models to know where a fire was, how active it was, and how much emissions it was putting into the atmosphere,” said Andy Edman, who oversees Western region wildfires for the National Weather Service. “It was sort of like having a family reunion. Most everyone is going to be acting normal, but wildfire behavior can be like your crazy uncle—erratic and difficult to predict.”
But a new experimental model that relies on data from National Oceanic and Atmospheric Administration (NOAA) and NASA satellites has proven remarkably good at simulating the behavior of wildfire smoke. The High-Resolution Rapid Refresh Smoke model, or HRRR-Smoke, builds on NOAA’s existing HRRR weather model, which forecasts rain, wind, and thunderstorms. It ingests real-time data from the Joint Polar Satellite System’s Suomi-NPP and NOAA-20 polar-orbiting satellites, as well as NASA’s Terra and Aqua satellites.
The image on the top left, captured by the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi-NPP, shows the Western United States in natural color in the afternoon on August 6, 2018, at the height of the Mendocino Complex Fire. On the top right is a HRRR-Smoke simulation from the same region at the same time.
Central to HRRR-Smoke is an important metric called fire radiative power. FRP is a measurement of the amount of heat released by a given fire in megawatts. A large fire, for example, might reach about 4,000 megawatts per pixel (750x750 meters). Calculating radiative power and where it is distributed can help scientists pinpoint the active front of a fire and predict the density and trajectory of the smoke it will emit.
The HRRR-smoke model combines FRP data with observations of wind speed, rain, and atmospheric temperature. It also includes vegetation maps because the more scientists know about what is burning, the better the simulation. (For instance, sagebrush burns differently than ponderosa pine.) These measurements are mapped to a three-dimensional grid that extends nearly 16 miles into the atmosphere. What results is a detailed forecast of the amount of smoke produced, the direction it should travel, and its plume height. HRRR-Smoke generates forecasts four times per day and looks ahead by 36 hours.
The forecasts include two key sets of predictions. “Near-surface smoke” refers to the smoke that will hover within 8 meters (26 feet) of the ground—the kind responsible for burning eyes and aggravated asthma. “Vertically integrated smoke” depicts all of the smoke in a vertical column, including smoke high in Earth’s atmosphere. That is the smoke you see at sunrise and sunset. The animation below shows a 36-hour forecast of vertically integrated smoke on August 6, 2018.

“Near-surface smoke is one indicator of air pollution, but the smoke could also be at much higher altitudes,” said Ravan Ahmadov, the main developer of the HRRR-smoke model, and a research scientist at NOAA’s Earth Systems Research Laboratory and the Cooperative Institute for Research in Environmental Sciences. “That’s important to know, because the smoke could affect visibility for aviation.” High-altitude smoke can also block incoming sunlight, which can cool air temperatures and interfere with solar energy production.
HRRR-Smoke is being used increasingly by forecasters and government agencies, but also by some local groups. During California’s Ferguson fire, the Department of Transportation used HRRR-Smoke simulations as part of its decision-making to suspend Amtrak rail service in the region. Likewise, the model was part of the National Park Service calculus when it closed parts of Yosemite.
On a local scale, schools in Utah referred to model forecasts when they opted to keep kids inside during recess and to cancel football games due to fires burning south of Provo. In Oregon, a youth swimming coach moved outdoor practice to an indoor pool after hearing the forecast.
“When we can tell people that the smoke is going to move in and hang around for a day, they can take smart actions to anticipate the event,” Edman said. “If you have a child with asthma, you’ll know to take precautions.”
The HRRR-Smoke model is still evolving. One limitation, Ahmadov said, is that each polar orbiting satellite passes each location in the continental United States just twice a day, and fires can spread and evolve rapidly during the time between those observations. He hopes to eventually incorporate data from geostationary satellites like GOES-16 and GOES-17, which have a lower spatial resolution but would scan the fires more often. The ultimate goal is to add smoke to the regular HRRR model used by the National Weather Service.
“In the next couple of years, I think we are going to see a lot of small, incremental improvements,” Edman said. “The model is not perfect, but all of the components came together this year, and the forecasts were pretty darn good.”

She liked some of the prior stuff I'd done featuring a model with an outfit such as this, so I happened to pull this outfit out of the suitcase I use to store random things that models may or may not want to pose in.
Strobist details: 285HV into a stripbox with the outer diffuser removed but the grid to the left front. 285HV with a purple gel into a octobox with the diffuser removed but the grid still on to the right rear. All optically triggered by the 144PC with black slide film over the front in my E-M5 Mark II's hotshoe. I was kinda standing over her, with a nice piece of satiny fabric.
en.wikipedia.org/wiki/Caesarea
Caesarea is believed to have been built on the ruins of Stratonospyrgos (Straton's Tower). Straton's Tower remained a Jewish city for two generations, until the Roman conquest of 63 BC when the Romans declared it an autonomous city. The city underwent vast changes under Herod the Great, who renamed it Caesarea in honor of the Roman emperor, Caesar Augustus. The place is open for visitors and it is quite magnificent!
