c_csc2sd(3NCARG)

💫 c_csc2sd — the NCAR Graphics girlies' guide to going from Cartesian to lat/lon 💫

okay bestie, sit down, grab a strawberry 🍓, because today we're talking about c_csc2sd from NCAR GRAPHICS — she lives in the 3NCARG manual section and she's literally the moment. her whole job? take your boring Cartesian coordinates and turn them into cute little latitudes and longitudes. it's giving glow-up, fr fr. 💅

✨ NAME ✨

c_csc2sd — convert from Cartesian coordinates to lat/lon coordinates. that's it, that's the gig, and she ate. 👑

---

🫶 FUNCTION PROTOTYPE 🫶

void   c_csc2sd(int, double *, double *, double *, double *, double *);

look at her. six args. no notes. ✨

---

🌸 SYNOPSIS 🌸

c_csc2sd(n, x, y, z, rlat, rlon);

---

🦋 DESCRIPTION 🦋

okay so here's who's who in the group chat:

• n — the number of input Cartesian coordinates. like, how many of them we're doing today. no cap.
• x — an array holding the X component of the Cartesian coordinates of your input data. and here's the tea: (rlat[i],rlon[i]) is the lat/lon coordinate that corresponds to the Cartesian coordinate (x[i],y[i],z[i]) for i=0 to n-1. iykyk. 💖
• y — an array holding the Y component of the Cartesian coordinates of your input data. same deal: (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. she's consistent, we love that. ✨
• z — an array holding the Z component of the Cartesian coordinates of your input data. and yeah, once again: (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. three besties, one truth. 🎀
• rlat — an array containing the latitudes of the output coordinates, in degrees. degrees!! don't forget!! 📐
• rlon — an array containing the longitudes of the output coordinates, in degrees. also degrees. matching set, iconic. 🌈

🔥 USAGE 🔥

so when do you call her? when you've got some Cartesian coordinates chillin' on a unit sphere and you're like "bestie, what are the equivalent lat/lon coordinates for these?" — that's c_csc2sd's whole main character moment. 🧚

the glow-up rules are:

• the Cartesian coordinate (1.,0.,0.) converts to lat/lon coordinate (0.,0.). periodt.
• latitudes and longitudes are assumed to be in degrees. always. 💜
• c_csc2sd is the double precision version of c_csc2s. so if you want more precision, she's your girl, no cap. ⭐

---

💀 RETURN VALUE 💀

c_csc2sd does not return a value. she gives you the coordinates through the arrays instead. it's giving "i don't chase, i attract" energy. 😌✨

---

💖 ACCESS 💖

to use c_csc2sd, load the NCAR Graphics library ngmath. that's the vibe check. go get her. 🫶
