While we're in the midst of developing several functions, they're not ready for public use just yet. I can make them available to you asap. I'd greatly appreciate your feedback to fine-tune the function interface. Regarding GFS data, could you please clarify how multiple variables are outputted to the Excel file? What's the structure of the Excel file, and what functions are necessary for each variable? Looking forward to your insights.
