Reading a rain gauge in inches is straightforward; the process involves checking the water level against the gauge's markings.
Here's a step-by-step guide:
-
Locate the Measuring Tube: Most rain gauges have a measuring tube inside a larger container. This tube is specifically calibrated to measure rainfall accurately.
-
Observe the Water Level: Look at the top of the measuring tube. You'll see markings (a scale) indicating inches (and sometimes fractions of an inch).
-
Read the Scale:
- The measuring tube can collect up to an inch of rainfall. According to the reference, "look at the top of the measuring tube, and you'll see a line with '1.00' beside it."
- If the rain comes up to that line, you've had an inch of rainfall.
- If the tube is not full, read the scale to determine how much rain fell. For instance, if the water level reaches the "0.50" mark, then half an inch (0.5 inches) of rain has fallen.
-
Empty After Reading: After recording the rainfall, empty the rain gauge to prepare it for the next rainfall event.
In summary, reading a rain gauge involves checking the water level against the marked scale on the measuring tube. If the water reaches the "1.00" mark, an inch of rain has fallen; otherwise, read the corresponding value on the scale.
