Dew will normally not collect on your skin, but it can form on your clothing and hair under the right conditions..
Yes, radiosonde instruments can measure dew points indirectly. They collect data on temperature and relative humidity as they ascend through the atmosphere. From these measurements, the dew point can be calculated using established formulas. This information is crucial for meteorological analysis and weather forecasting.
This process is called dew formation. Dew forms when the surface cools down during the night, causing water vapor in the air to condense and collect as droplets on cooler surfaces.

The dew point is the temperature at which air becomes saturated with water vapor. To find the dew point, you would first calculate the vapor pressure using the mixing ratio, then convert the vapor pressure to the dew point temperature using a psychrometric chart or equation. Without the vapor pressure or more information, the dew point cannot be determined.
To survive in a desert using condensation, you can create a simple solar still by digging a small hole in the ground and placing a container at the bottom to collect water. Cover the hole with clear plastic sheeting, sealing the edges with soil to trap moisture. As the sun heats the ground, moisture from the soil will evaporate, condense on the underside of the plastic, and drip into the container. Additionally, you can gather dew in the early morning by placing a cloth on the ground and wringing it out later.
The dew point is the temperature at which air becomes saturated with moisture and dew forms. It can be determined by using a hygrometer to measure the humidity in the air and then using a dew point calculator or chart to find the corresponding temperature at which dew will form.

First of all, the 'sweat' on a cold drink container is condensation. Condensation occurs when there is sufficient humidity in the air, and that air is cooled below the dew point. This is exactly what happens with a cold drink container in the summer. In summer there is usually fairly high humidity, but even more important, that moisture is warm, and is easily cooled (by the cold drink container) to a temperature that is below the dew point, and . . . . . water droplets begin to collect on the container's surface. Once the container warms to a temperature above the dew point, you will see the 'sweat' is gone.

If you live somewhere where you have humidity, a trip outside early in the morning will lead you to find dew on leaves and grass. You could brush the dew off the leaf into a small bowl or jar. It won't be much liquid.
When warm air comes into contact with a cool surface, it loses heat and its moisture condenses into liquid droplets. This process, known as condensation, occurs because the temperature of the container is cooler than the dew point of the air inside. The moisture in the air transitions from vapor to liquid as it cools, causing it to collect on the container's surface.
