South American Weather Forecast Meteograms for 26 Locations

CPTEC provides forecast model meteograms for 26 locations across South America. The dataset contains time-series forecasts for parameters like relative humidity and surface temperature, extending from the initial time out to six days. Forecasts from the most recent run and the previous 36 hours are available.

Use Cases

• Analyze trends in Relative Humidity (%) and Surface Temperature (C) forecasts to validate model performance against observations.
• Compare Precipitation (mm/h) forecasts across different South American locations to study regional precipitation patterns.
• Model the relationship between Mean Sea Level Pressure (mb) and Surface Wind (m/s) forecasts for atmospheric dynamics research.
• Use the six-day forecast time steps to train sequence prediction models for meteorological parameters.
• Assess forecast consistency by comparing the most recent forecast run with data from the previous 36 hours.

Strengths

• Covers 26 distinct locations across South America.
• Provides forecasts for 5 key atmospheric parameters.
• Forecast time steps extend out to six days from the initial time.

Limitations

• Specific row count, sample size, and data volume are unknown.
• Geographic coverage is limited to 26 points in South America, not continent-wide.
• Data freshness depends on forecast run cycles; update frequency is unspecified.
