Now the weather blaster straight forward enough, blow up, hang the burden, let go! But this is not a category of balloons that we talk about no, for a weather balloon, whether it's a meteorological balloon or camera, there are a few things to keep in mind when organizing your launch:  Size matters
Do not be tempted to buy a smaller balloon and just pump more helium! The ball is going up to 90 feet from the ground. At high altitudes, balloons due to pressure increase without reducing the pressure inside. As your bladder rises through the atmosphere it will expand as the air blows. A 5-foot windbreaker on launch will reach a width of 20 feet at the maximum height. There is a need for an increase in inflation for this. The ball will always shoot, hopefully at the maximum height. It will not get this if you fill it. So get the right balloon to take the weight of the radio station or the weather blister of the camera – of course, if your balloons are high above what you need, because you have some fluid rooms and can experiment with inflation but at your own risk!
Each cubic meter of helium will lift 28g of weight, although the radio station needs to be lighter than this for the weather blower to rise. The blister will rise faster the smaller the weight. The difference between the radio power weight and the weight of the truck is called the "free lift". You can calculate the blister cleaner easily as it works at 300ft per minute for each pound of "weight" and # 39;. The faster your balloons increase, the less likely there is something going wrong – blow out, battery equipment fails, charging ends up further down the wind and is harder to recover.
Now does the weather balloon not weigh much right? Put it in your pocket almost (if you have very large pockets). But helium cans do it! It is a big heavy steel tank and a 125 cubic meter helium cable will stand about 6 feet tall and weighs hefty 100 pounds. So you need a car or a jeep for transportation, especially if you keep track of your burden when it comes to landing.
It's no frustration but losing your charge, especially if you can not afford the device to stream the images / data right back. If you rely on GPS tracking to retrieve your data manually, think better of the poor electronics that shake into the freezing point in the upper part of the earth! At 90 ° C the temperature is approximately -50 degrees and the average battery will stop working. However, you have a better chance of keeping in touch with your beloved balloon device if you are using lithium batteries NOT lithium batteries. No no, different kettle of fish. You can buy lithium batteries and they are 8 times longer than normal, but more importantly they can withstand the cold level of the upper stratosphere!
Now, on the day you need to consider launching the area and weather conditions: Do not boot near the military base! They might think they are under attack, and while the idea of a camouflage around a red alert may sound funny for you, I bet that the idea of shooting down the weather ball is not! Do not disturb military airspace and they will not bother you. Next, make sure your launcher is away from obstacles like trees and calls, preferably not in a built-up area for reflection.
For obvious reasons, no wind is optimal, but look for the wind direction before starting to know what direction it is. If you start the camera then you have a sunny day for a good exposure to your aerial photographs.
