The data you are looking for is available in the following link and can be downloaded in this ascii format using the OpenDAP. (just copy paste the url below):

https://www.ncei.noaa.gov/thredds-ocean/dodsC/pathfinder/Version5.3/L3C/2022/data/20220403021723-NCEI-L3C_GHRSST-SSTskin-AVHRR_Pathfinder-PFV5.3_NOAA19_G_2022093_night-v02.0-fv01.0.nc.ascii?lat%5B1570:1:1570%5D,lon%5B2455:1:2455%5D,sea_surface_temperature%5B0:1:0%5D%5B1570:1:1570%5D%5B2455:1:2455%5D,time%5B0:1:0%5D

Remember SST = (value)0.01 (in Deg celsius) SST = (value)0.01 + 273.15 (in Kelvin)

Now if you see the link (above), The yellow highlighted portion (1570:1:1570, twice) is for Latitude range (0:1:4319) and the green highlighted portion (2455:1:2455, twice) is for the Longitude range (0:1:8639). The data is 0.04 deg resolution therefore you can change these values in the highlighted section to get your desired lat/lon range.

e.g. this is nighttime only example (just copy paste the url):

https://www.ncei.noaa.gov/thredds-ocean/dodsC/pathfinder/Version5.3/L3C/2022/data/20220403021723-NCEI-L3C_GHRSST-SSTskin-AVHRR_Pathfinder-PFV5.3_NOAA19_G_2022093_night-v02.0-fv01.0.nc.ascii?lat%5B1570:1:1575%5D,lon%5B2455:1:2455%5D,sea_surface_temperature%5B0:1:0%5D%5B1570:1:1575%5D%5B2455:1:2455%5D,time%5B0:1:0%5D

gives the data from 6 latitudes ranging from (24.562454, to 24.354122) for only longitude -77.68743 (yellow changed to 1570:1:1575, green is the same)

You can get the same data from NOAA Coastwatch ERDDAP servers: a) https://coastwatch.pfeg.noaa.gov/erddap/griddap/nceiPH53sstn1day.html. (for daytime data) b) https://coastwatch.pfeg.noaa.gov/erddap/griddap/nceiPH53sstn1day.html (for night data)

Using R-code is also another way you can access the data through THREDDS server without actually downloading the data: for details see:

[SimonDedman]

as per the lat lon values it is not very straight forward you have to put those numbers considering the latitudes are between 89.979 to -89.979 (i.e. 0.04 degree resolution therefore 4320 values in total), the value 2455 actually corresponded to 24.562454 deg N, and Longitude being between -179.979 and 179.979 (0.04 deg resolution with 8640 values), the number 1570 actually corresponds to -77.68743. If you play around those numbers in the URL you will find values at different lat/lon.

Instead

I would suggest using NOAA Coastwatch ERDDAP servers: https://coastwatch.pfeg.noaa.gov/erddap/griddap/nceiPH53sstn1day.html. As you do not have to guess the grid number just put the date and the lat/lon values you will get your data in any available format you need. SEE the snapshot here: image.png

This snapshot above provides a .ascii file as below when you click submit: image.png

If you use the ERDDAP website then you do not have to guess that lat/lon grid number and you will directly get the SSTs in degree celsius (no conversion is needed).
