Hi @vidguy7, Here are links to the topics that discuss your questions: > [@vidguy7](#): > > Has anyone tried a coating of car wax? > [@SKY / Tempest: wind sensor initial self balancing](https://community.tempest.earth/t/sky-wind-sensor-initial-self-balancing/828/11): > > Thanks Sam. Actually, our solution is a bit more technical than you might imagine. All sonic anemometers face the challenge of dealing with obstructions in the sonic path. Even slight changes in the sonic path distance can throw off the timing of the return sonic signal. To deal with obstructions like rain drops, we have developed an algorithm that inspects all wind data in real-time. Any data that looks suspect (by virtue of algorithmic rules, which will get better and better with more data) g… > [@vidguy7](#): > > a long lag time for humidity > [@Temperature/humidity response time](https://community.tempest.earth/t/temperature-humidity-response-time/2601): > > We recently had an unusual phenomenon, when a cold front dropped the temperature by 9° C in a matter of about two minutes. This was confirmed by both my Davis and Oregon stations. In both cases, Weather Display showed the drop over about five minutes, with a slight delay due to the thermal inertia of the sensors. WeatherFlow took over an hour to respond to the change of temperature. I believe this to be due to the thermal inertia of AIR with the mass of the batteries. The question is whether t… I have not witnessed or read about anyone having a delay with their pressure reading.

We agree that having to fudge your elevation to calibrate your sea level pressure is NOT THE RIGHT APPROACH…and to be clear, this is not the approach that WF is taking. Here is how it actually works: AIR will sense the pressure at it’s location (station pressure). To normalize and compare against other stations in the area, total elevation needs to be taken into consideration…which is then used to calculate sea-level pressure…so that everyone is comparing apples to apples. … > [@vidguy7](#): > > wind velocities as I rotated the pole my Sky > [@SKY / Tempest: wind sensor initial self balancing](https://community.tempest.earth/t/sky-wind-sensor-initial-self-balancing/828): > > Your SKY / Tempest leaves the factory with a wind sensor calibration in place. To ensure in-situ accuracy, the sonic wind sensors in SKY / Tempest are designed to self-calibrate over time once installed in the field. The initial in-field process requires collecting a certain amount of data at all four cardinal points. This initial process runs through a check to ensure all four sonic sensors are balanced properly.

Gizmoev, in the case you cite, the issue seems to be less with the flat area under the sensors as opposed to water collection on the sensors themselves. I wonder if that was the causative factor in my increased wind velocities as I rotated the Sky unit’s mounting. I looked at the flat area and it was clean (I had previously cleaned it), but I didn’t focus on the sensors themselves. I wonder how the pricey units deal with this? It would seem that no matter how slick the flat area is, unless something is changed to the sensors themselves, the example you gave will continue. ---

Ian, thanks much. I have tried using the search tool, but it often didn’t come up with the answers. I’ll definitely dig into your links. ---

Welcome @vidguy7 . Great to have another met / scientist aboard. You’re in very good and helpful company here with the other owners. A few observation which may or may not have been addressed: 1. when viewing graphs, make sure to zoom into the 1min resolution to see the finest data. See [Data archive buckets explained](https://community.tempest.earth/t/data-archive-buckets-explained/1063). 2. Rotate your phone to landscape when viewing graphs. 😉 3. Your observed issue with wind spikes during rain events is due to drops in the sonic path. We are experimenting with various coatings. So far the super hydrophobic nano-particle varieties are performing the best. Many of the pricey sonic anemometers use similar. We’ll solve it, have patience. 4. To ensure data integrity across the entire network, we believe in in-situ calibration and ongoing dynamic QC. To that end, we have/are deploying a Continuous Learning (CL) system for various parameters. In short, we compare data from your station to reference data sources in your immediate area and apply daily calibrations when warranted. For example see [CL for Humidity explained](https://community.tempest.earth/t/cl-for-humidity-explained/2840) As of 23 Jan, your station has received an initial calibration for Humidity on 23Jan. The system is still collecting and certifying comparison data for Pressure, UV, and Rain before initial corrections are applied. We’re glad you found us. Welcome. ---

WF staff, is there a set time of day that calibrations are applied, if necessary? Thanks Ken ---

> [@vidguy7](#): > > WF staff, is there a set time of day that calibrations are applied, if necessary? It varies dependent on run times, comparison data availability, modeling, etc, etc. Humidity, Pressure, and UV are now run daily. Rain will likely run hourly in CONUS to start. After the first couple calibrations, the subsequent tweaks become more and more subtle. ---

I have noticed similar behavior with the graphs but found that at least sometimes it seems to be a function of granularity. Some of the numbers change significantly when you zoom in or zoom out in the graph. As I zoom in deeper, the graph gets ever closer to the raw numbers. ---

Is there a way to hide the lightning card? I did a search and can’t find anything on that. Is it only the battery & forecast cards that have that ability? ---

Nope there is no way to hide the lightning card. You can disable the lightning notifications though. ---

Peter, thanks. Yes, I had already disabled those. As a 2nd best approach, I moved the lightning cards to the bottom. [Previous page](https://community.tempest.earth/t/new-owner-pro-con-observations/3017.md?page=1)
