I know that the next generation jet engines are a lot different from the previous so I have to assume that nexrad, next generation radar, is also a lot different than the previous.
Are they the same then? Do they both involve iridium satellites?
Is my weather station not interested in cloud optical depth?

Actually, you don't even need to test. In order to do any cloud seeding operation, you need to get a permit. Just go to the permit department and ask. It's there for public record. Since it's not secret, it's not nefarious, and it's not (of the devil), youo should have no problem gaining the information you seek.
But in the event that you don't find the smoking gun, look up (polar vortex) and then (Jet stream). That may point you in a find direction to comprehension.
I don't care about how ludicrously easy it is to do something so harmful to all life on earth and the environment.
9) Does cloud seeding have any significant negative environmental impacts?
There is no evidence that suggests cloud seeding creates any significant negative environmental impacts on the environment. Measurements made since the 1950’s indicate that the amount of silver iodide deposited in a target area after a long standing cloud seeding project falls several orders of magnitude (multiples of 10) short of the amount known to be toxic to plants, animals, trees, or humans. It is often difficult to detect any silver accumulation above the background amounts naturally present in the environment. Naturally, this kind of investigation continues. See FAQ #10, “Is Silver Iodide Harmful to the Environment?”
Warm cloud seeding is not conducted nearly as frequently as silver iodide cloud seeding, and the effect of warm cloud seeding agents on the environment is not as well known. Warm cloud seeding agents are salts. Preliminary results suggest that because the amounts of seeding agent used are so small, even these warm cloud seeding materials probably do not have any significant impacts.
10) Is silver iodide harmful to the environment?
As noted in the previous response (with respect to cloud seeding), questions sometimes arise regarding the environmental effects of silver iodide aerosols used in cloud seeding, which include silver iodide aerosol complexes such as silver iodide-silver chloride. Silver iodide is the primary component of silver iodide-based ice-nucleating complexes used in cloud seeding, and all these complexes will be referred to as silver iodide (AgI). The published scientific literature clearly shows that no environmentally harmful effects arising from cloud seeding with silver iodide aerosols have been observed; nor would they be expected to occur. Based on this work, the WMA finds that silver iodide is environmentally safe as it is currently being dispensed during cloud seeding programs. (See the WMA’s 2009 Position Statement on “The Environmental Impact of Using Silver Iodide as a Cloud Seeding Agent”, www.weathermodification.org.)

Sorry, the fog is not natural, smells like chemicals and it snowed at 6 above.

What we need to the testing for, is to find presence of the chemicals used, such as silver nitrate and then sue their buttsides off, even criminal charges. Its time to stop this once and for all.

Thanks.

Depends on whose radar you're asking about - it's next generation for weather radar. Not so much for military stuff. The NEX part of NEXRAD is more how you process the returns, it's also got some neat extra bits for doing Dopplers on different polarizations and the like, but the difference is mostly in the processing. It's not as advanced, say, as a really agile steered beam setup like an AESA.
And no, no radar involves Iridium satellites. Iridium satellites are voice grade comm links with the ground. Or very low speed data links. At $1 to $2 a minute.
Is my weather station not interested in cloud optical depth?
Ask them.
NEXRAD (Next Generation Radar) obtains weather information (precipitation and wind) based upon returned energy. The radar emits a burst of energy (green). If the energy strikes an object (rain drop, bug, bird, etc), the energy is scattered in all directions (blue). A small fraction of that scattered energy is directed back toward the radar.
Q: In the Non-Precipitation Echoes module, chaff is described as having low reflectivity. From my experience, chaff usually has very high reflectivity values. Areas of chaff often look like thunderstorms at first glance. Can you explain this discrepancy between the training material and what we see locally?
A: The Non-Precipitation Echoes module had no intention of setting reflectivity thresholds regarding chaff. In fact, chaff can appear on radar as just about any reflectivity value. From the point of view of the training, Correlation Coefficient (CC) and Differential Reflectivity (ZDR) are the important parameters.

So traditional chaff (not nano) could certainly show up on NEXRAD. This would happen through a combination of errors i.e. chaff deflected returns which did not get differentiated by the operator or automatic editing from precipitation and so get presented in the view we see.
Nano aluminum chaff is going to be very reflective because of its' out of proportion surface area. There is a hint of this in the following Q&A...
So the questioner is telling them that their reflectivity values are trash and don't hold true in real life observation.
AESA is basically a cloaked communication system using a phased array?? I'm not sure how this system would employ chaff.

PERIOD.
The federal government collects information about what is going on in the environment to help Canadians make decisions every day. It monitors many different aspects of the environment, including solar flares, weather, air quality, migratory birds, fish, insects that carry human diseases, forests, water quality and quantity, changes in permafrost, and the ecology of national parks.
How so?
Cloud seeding along with other weather mitigation processes use combustion which produces ultra-fine (nano size) particles.
