Download for a 1-month free trial. The first 3D radar on iPhone® and iPad®, Weather Lab is for meteorologists, storm chasers, atmospheric scientists, pilots or weather enthusiasts that want more than just a friendly forecasting app and are looking to get the most out of weather radar data. We serve the most up to date data directly from NOAA to provide the most up to date information possible.

There are two levels of Weather Lab:

Weather Lab: Gives you the richness, power, and fluid control you demand to help you gain an advanced model of weather events across the country.
• Reflectivity and the radar views of scan (lowest scan) and volume
• National Weather Service (NWS) alerts
• True 3d weather radar views

Weather Lab PRO (In-app Subscription): Everything from Weather Lab, plus:
• Up to 15 scans per volume
• Horizontal and Vertical volume slicing
• Velocity, Differential Reflectivity, Correlation Coefficient, and Spectrum Width

See the comparison chart:

The ability to view radar in 3D helps create a better mental model and improves situational awareness. Interacting with a more natural and fluid 3D environment assists you with the analysis of this complex visual information. To make this possible, we built it using Apple's high-performance Metal graphics layer.

Gain deeper insights by displaying and cutting through radar volumes in different ways:

Scan - Display radar in the form in which it was captured: A full circle scan pointing into the sky at a constant elevation angle. [Weather Lab: Lowest scan. Weather Lab PRO: Any scan in the current VCP.]

Volume - View the radar as four combined 3D isosurfaces, giving you the at-a-glance ability to understand the big picture.

Horizontal Slice (Weather Lab PRO) - Since any given scan ascends through the altitudes at an angle, a mental leap is required to understand what is happening at a single altitude. Now you have the ability to see a specific altitude.

Vertical Slice (Weather Lab PRO) - Cut through the radar volume vertically, creating a "wall" of data to allow instant interpretation of what is happening through all altitudes at once.

Level 2 NEXRAD Radar:
• Reflectivity
• Velocity (Weather Lab PRO)
• Differential Reflectivity (Weather Lab PRO)
• Correlation Coefficient (Weather Lab PRO)
• Spectrum Width (Weather Lab PRO)

NWS Warnings:
• Tornado
• Severe Thunderstorm
• Flash Flood
• Special Marine

Contiguous United States: 143
Alaska: 7
Hawaii: 4
Republic of Korea: 2
Guam: 1
Japan: 1
Puerto Rico: 1
Total: 159

NEXRAD radars continuously scan a 3D picture of the skies using one of several predetermined volume coverage patterns (VCP). Weather Lab provides you access to all scans in the volume, giving you the full spatial picture from which to visualize the structure of a storm.

Needs some tweaks, but great potential!

Don’t get me wrong, this is a great app that has lots of potential. BUT I feel like this was released a bit soon. There are some small tweaks that really should’ve been in the initial release, like being able to make the compass point north by tapping it, the ability to show your current location on the map and go to the closest radar site, and show storm cell info and tracks. Also on my wish list, but not as important to me: lightning strikes, showing smaller towns’ names, and the ability to customize the radar colors. Also, I’ve noticed the radar image not updating when I return to the app after a while. I have to force close the app and open it back up to see the latest image. With all that said, this app is beautiful...the 3D graphics and smoothing are nice features that we haven’t seen before on this class of iPhone app. And as features are added, I could see this being the iOS equivalent of GRLevel2, and I can’t wait to see where it goes!

Ur boi, weather obsessed kid ,

A must have - yet needs more thought.

I had to get this amazing app when I saw it. No other mobile app has such features! It’s incredible. This can beat Radar Scope in so many ways! On the other hand, It was a bit of a let down to find that some simple features are only in pro. Now, i do know how it does not cost anything to acquire radar data from the NWS. Therefore, velocity should be included free. People who will purchase this app will purchase because of its 3D feature and that’s what pro should hold most of. So it would make sense to pay for the stuff you guys have to render and “work” on. It’s kind of stealing, people pay for free data. To conclude, leave NEXRAD reflectivity and velocity free, along with volumetric and cut through. And then pay for the rest go the radar data’s and 3d features. Thanks for making this awesome app!

Weather lab is awesome

I love being able now to look at storms looking through it from the side, instead of just looking at it from an above view angle.

There are only a couple things I would like to be able to do, and they are an ability to measure how far away from a certain location a storm is, and the ability to switch the map from a city view to a county view. I know of no weather apps that do this, and being a storm chaser, every warning is put out with naming the counties involved, with a sub-naming the cities that a storm is heading for.

Thanks for making this app, it store beats spending a great amount more for a program like it.
