✨ cnvgrib1to2 — bestie's guide to glow-ups for weather files ✨

okay so real talk, this is the cnvgrib1to2 manual page from section 1 (General Commands Manual, if you're keeping score 🎀). she converts GRIB1 files into GRIB2 files. that's it. that's the whole personality. and honestly? iconic. 💅

🌸 NAME 🌸

cnvgrib1to2 — Convert a GRIB1 file to GRIB2 format

like. the name literally tells you what it does. no cap.

---

✨ SYNOPSIS ✨

cnvgrib1tos21 <grib2filename> <grib1filename> [packing_scheme]

bestie I need you to look at that command name very closely. the manual says cnvgrib1tos21. yes, with the s21 in there. I am NOT fixing it, I am NOT "correcting" it, we are simply reporting it exactly as the page does. do not come for me, I'm just the messenger 🫶

🦋 DESCRIPTION 🦋

okay so what are we actually doing here. This program takes a GRIB1 format file and converts it into a GRIB2 format file. that's the assignment. she ate and left no crumbs. 💖

now, GRIB — for those of us who didn't wake up knowing this — is a file format that was defined for meteorological data, and it was defined by the WMO, aka the World Meteorological Organisation. so like, weather girlies and atmospheric scientists, this one's for you 🌈🌦️

👑 OPTIONS 👑

so this program takes an optional packing_scheme, and bestie, you have choices. it may be one of these:

• grid_simple — the simple grid packing scheme ✨
• grid_complex — the complex grid packing scheme 💫
• grid_complex_spatial_differencing — the complex grid packing scheme, but with spatial differencing 🌀
• grid_jpeg — the JPEG grid packing scheme 🖼️
• grid_png — the PNG grid packing scheme 🎀

and the default? the default is grid_jpeg. so if you just... don't pick one? she's gonna go JPEG on you. no further questions. 💅
