c_csc2s(3NCARG)

✨ c_csc2s — the NCAR GRAPHICS glow-up ✨

okay bestie, welcome to the 3NCARG section of the manual, where we're talking about c_csc2s 💖 she's a C function, she's iconic, and she converts from Cartesian coordinates to lat/lon coordinates. no cap.

---

🌸 NAME 🌸

c_csc2s — convert from Cartesian coordinates to lat/lon coordinates. that's it, that's the job, and she does it flawlessly 💅

---

🎀 FUNCTION PROTOTYPE 🎀

void   c_csc2s(int, float *, float *, float *, float *, float *);

look at her signature. six arguments. absolutely serving function-prototype realness ✨

---

🦋 SYNOPSIS 🦋

c_csc2s(n, x, y, z, rlat, rlon);

---

💜 DESCRIPTION 💜

okay so let's meet the cast, one by one 🫶

• n — the number of input Cartesian coordinates. like, how many points are we doing today bestie.
• x — an array holding the X component of the Cartesian coordinates of the input data. and here's the vibe: (rlat[i],rlon[i]) is the lat/lon coordinate corresponding to the Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1. yes literally, every single i from 0 all the way up to n-1, no skipping 🙈
• y — an array holding the Y component of the Cartesian coordinates of the input data. same deal, same energy: (rlat[i],rlon[i]) is the lat/lon coordinate corresponding to the Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1. 🌈
• z — an array holding the Z component of the Cartesian coordinates of the input data. and once again, for the people in the back: (rlat[i],rlon[i]) is the lat/lon coordinate corresponding to the Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1. the trio x, y, z really said "we're a package deal" 👑
• rlat — an array holding the latitudes of the output coordinates, in degrees. not radians, bestie, degrees.
• rlon — an array holding the longitudes of the output coordinates, in degrees. also degrees. always degrees. ⭐

✨ USAGE ✨

so when do you call her? c_csc2s gets called when you need to find the equivalent lat/lon coordinates to specified Cartesian coordinates on a unit sphere 🌐 (unit sphere!! she's small but mighty).

and here's the iconic mapping you need to memorize, fr fr: the Cartesian coordinate (1.,0.,0.) is converted to lat/lon coordinate (0.,0.). that's the anchor, that's the blueprint, that's the moment 💫

also, latitudes and longitudes are assumed to be in degrees. keep that in your notes app 📝

---

🔥 RETURN VALUE 🔥

c_csc2s does not return a value. she gives you everything through her output arrays instead — main character energy, honestly 😌 no return value needed when you're this booked and busy.

---

🌈 ACCESS 🌈

to use c_csc2s, load the NCAR Graphics library ngmath. that's the one. don't forget her at the linker, she will not show up otherwise 💀

okay that's the whole page!! this was c_csc2s(3NCARG) from the NCAR GRAPHICS manual, and the source/version + date at the bottom of the original page said UNIX and MAY 2000 — so that's the vintage, that's the era, and honestly? she aged like fine wine 🍷🦋 bye bestie, go convert some coordinates 💅✨
