Weather prediction accuracy can make or break critical decisions. Whether you're planning agricultural operations, managing energy distribution, or coordinating emergency response, understanding how well your forecasting models perform is essential. Traditional weather analysis often requires specialized meteorological software and complex statistical knowledge.
With Sourcetable, you can analyze weather prediction accuracy, compare forecasting models, and identify patterns in meteorological data using familiar spreadsheet tools enhanced with AI-powered insights. No need for specialized software or advanced statistical training.
Calculate RMSE, MAE, and bias statistics automatically. Compare multiple forecast models side-by-side with instant statistical summaries.
Generate heat maps, scatter plots, and time series charts to identify seasonal patterns, model biases, and forecast reliability trends.
Connect to weather APIs, import CSV files, or paste data directly. Sourcetable handles various data formats and updates automatically.
AI-powered analysis identifies unusual prediction errors, extreme weather events, and model performance outliers automatically.
A regional weather service wanted to evaluate their 7-day temperature forecasting accuracy across different seasons. Using Sourcetable, they imported actual temperature readings alongside predicted values for 365 days of data.
The analysis revealed that their model consistently over-predicted temperatures by 2.3°F during winter months but maintained excellent accuracy (within 1°F) during summer. This insight led to seasonal calibration adjustments that improved overall forecast reliability by 18%.
An agricultural planning company needed to compare three different precipitation forecasting models to determine which provided the most reliable 5-day rainfall predictions for crop irrigation scheduling.
By analyzing 18 months of forecast vs. actual precipitation data in Sourcetable, they discovered that Model A excelled at predicting light rain (under 0.5 inches) with 89% accuracy, while Model C was superior for heavy precipitation events (over 1 inch) with 76% accuracy. They now use a hybrid approach, switching models based on predicted precipitation intensity.
A wind farm operator analyzed 2 years of wind speed predictions against actual turbine performance data to optimize energy production forecasting. The Sourcetable analysis revealed that forecast accuracy dropped significantly during transitional seasons (spring and fall) when weather patterns are most variable.
This finding prompted them to implement more conservative energy production estimates during these periods, reducing over-commitment to the power grid by 23% and avoiding costly penalties for underdelivery.
Upload forecast and actual weather data from any source - CSV files, weather APIs, or manual entry. Sourcetable automatically recognizes date formats and weather parameters.
Define your analysis parameters: forecast lead times, geographic regions, weather variables, and time periods. Create comparison groups for different models or locations.
Calculate standard meteorological accuracy metrics like RMSE, MAE, correlation coefficients, and skill scores. Sourcetable computes these automatically with proper statistical methods.
Create professional charts showing forecast performance over time, seasonal variations, and model comparisons. Export results for reports or presentations.
Evaluate frost warnings, rainfall predictions, and growing degree day forecasts to optimize planting schedules and irrigation planning.
Assess temperature and wind forecasts for demand prediction and renewable energy output estimation across seasonal cycles.
Analyze visibility, wind shear, and turbulence forecasts to improve flight safety planning and route optimization decisions.
Evaluate severe weather warnings, hurricane track predictions, and flood forecasts to enhance disaster response planning.
Analyze extreme weather prediction accuracy to refine catastrophic risk models and improve actuarial calculations.
Assess road condition forecasts, visibility predictions, and precipitation timing to optimize shipping schedules and route planning.
Sourcetable accepts CSV files, Excel spreadsheets, JSON from weather APIs, and direct data paste. Common formats include NOAA data files, European Centre forecasts, and custom meteorological datasets with timestamps and location coordinates.
Sourcetable automatically computes standard meteorological verification metrics including RMSE, MAE, bias, correlation coefficients, and categorical skill scores. Simply specify your forecast and observation columns, and the system generates comprehensive accuracy statistics.
Yes, Sourcetable handles ensemble forecast data by calculating spread metrics, probability distributions, and uncertainty quantification. You can analyze how ensemble spread relates to forecast accuracy and identify optimal probability thresholds.
Create comparison tables showing side-by-side accuracy metrics for each model, generate skill score differences, and use statistical significance tests. Sourcetable's visualization tools help identify which models perform best under different weather conditions.
Use Sourcetable's time series analysis tools to group accuracy metrics by month, season, or weather regime. Create seasonal accuracy profiles and identify periods when specific models perform better or worse than average.
Yes, set up automated data imports from weather APIs, create template analysis workflows, and schedule regular accuracy reports. Sourcetable can generate updated forecast verification statistics as new data becomes available.
To analyze spreadsheet data, just upload a file and start asking questions. Sourcetable's AI can answer questions and do work for you. You can also take manual control, leveraging all the formulas and features you expect from Excel, Google Sheets or Python.
We currently support a variety of data file formats including spreadsheets (.xls, .xlsx, .csv), tabular data (.tsv), JSON, and database data (MySQL, PostgreSQL, MongoDB). We also support application data, and most plain text data.
Sourcetable's AI analyzes and cleans data without you having to write code. Use Python, SQL, NumPy, Pandas, SciPy, Scikit-learn, StatsModels, Matplotlib, Plotly, and Seaborn.
Yes! Sourcetable's AI makes intelligent decisions on what spreadsheet data is being referred to in the chat. This is helpful for tasks like cross-tab VLOOKUPs. If you prefer more control, you can also refer to specific tabs by name.
Yes! It's very easy to generate clean-looking data visualizations using Sourcetable. Simply prompt the AI to create a chart or graph. All visualizations are downloadable and can be exported as interactive embeds.
Sourcetable supports files up to 10GB in size. Larger file limits are available upon request. For best AI performance on large datasets, make use of pivots and summaries.
Yes! Sourcetable's spreadsheet is free to use, just like Google Sheets. AI features have a daily usage limit. Users can upgrade to the pro plan for more credits.
Currently, Sourcetable is free for students and faculty, courtesy of free credits from OpenAI and Anthropic. Once those are exhausted, we will skip to a 50% discount plan.
Yes. Regular spreadsheet users have full A1 formula-style referencing at their disposal. Advanced users can make use of Sourcetable's SQL editor and GUI, or ask our AI to write code for you.
