How to play StationPlot Sprint

Decode a station model

1. Read the temperature at upper left and dew point at lower left.
2. Restore the three-digit pressure code to a full sea-level pressure. Add 10 before codes below 500, add 9 before codes at or above 500, then place the decimal before the final digit.
3. Read the staff direction, count wind-barb feathers, and estimate the filled fraction of the central cloud-cover circle.

Plot a written observation

1. Read the observation sentence above the answer fields.
2. Enter the two temperatures, convert pressure to its three-digit code, and choose wind direction, wind speed, and cloud cover.
3. Watch the code-native station model update, then select Check answer.

Understand feedback and scoring

Each round contains six scored fields. A field that is correct on the first check earns 10 points. The maximum score is 600 across ten rounds. Accuracy is the percentage of checked fields answered correctly. Selecting New round before checking records the skipped round with no correct fields.
