'Wet' snow vs. 'dry' snow. The size and make up of a snowflake depends on how many ice crystals group together and this will be determined by air temperatures. Snowflakes that fall through dry, cool air will be small, powdery snowflakes that don't stick together.

3 Adjusting the calibration interval In response to customers seeking to reduce instrument cost-of-ownership, we have developed a formal âcalibration interval extensionâ process. The process has two major steps: checking for data sufficiency and, if enough data is avail-able, performing detailed statistical analyses. Part 2: Performing the statistical analyses If the model under review passes the data-sufficiency tests, then the statistical analyses can proceed. The specific methodology depends on three things: the type of instrument, the length of the existing calibration interval and the sample size.
