+GFS V16.3.15 RELEASE NOTES
+
+-------
+PRELUDE
+-------
+
+OBSPROC is updated to v1.2 in operations. This upstream dependency results in a version increase for the GFS.
+
+This OBSPROC update adds the following:
+
+* high-vertical resolution radiosonde profiles (up to 255 pressure levels) to the global and RAP prepbufr files
+* high-vertical resolution radiosonde profiles (full profiles) to the newly established global and RAP *uprair* bufr dump files
+* high-spatial and temporal resolution hurricane tailored winds for the HAFS model in the *satwhr* buff dump files
+
+It also increases the amount of msonet observations across all regional models.
+
+IMPLEMENTATION INSTRUCTIONS
+---------------------------
+
+The NOAA VLab and the NOAA-EMC and NCAR organization spaces on GitHub .com are used to manage the GFS code.  The SPA(s) handling the GFS implementation need to have permissions to clone VLab Gerrit repositories and private NCAR UPP_GTG repository. All NOAA-EMC organization repositories are publicly readable and do not require access permissions.  Please proceed with the following steps to install the package on WCOSS2:
+
+```bash
+cd $PACKAGEROOT
+mkdir gfs.v16.3.15
+cd gfs.v16.3.15
+git clone -b EMC-v16.3.15 https://github.com/NOAA-EMC/global-workflow.git .
+cd sorc
+./checkout.sh -o
+```
+
+The checkout script extracts the following GFS components:
+
+| Component | Tag         | POC               |
+| --------- | ----------- | ----------------- |
+| MODEL     | GFS.v16.3.1   | [email protected] |
+| GLDAS     | gldas_gfsv16_release.v.2.1.0 | [email protected] |
+| GSI       | gfsda.v16.3.12 | [email protected] |
+| UFS_UTILS | ops-gfsv16.3.0 | [email protected] |
+| POST      | upp_v8.3.0 | [email protected] |
+| WAFS      | gfs_wafs.v6.3.2 | [email protected] |
+
+To build all the GFS components, execute:
+```bash
+./build_all.sh
+```
+The `build_all.sh` script compiles all GFS components. Runtime output from the build for each package is written to log files in directory logs. To build an individual program, for instance, gsi, use `build_gsi.sh`.
+
+Next, link the executables, fix files, parm files, etc in their final respective locations by executing:
+```bash
+./link_fv3gfs.sh nco wcoss2
+```
+
+Lastly, link the ecf scripts by moving back up to the ecf folder and executing:
+```bash
+cd ../ecf
+./setup_ecf_links.sh
+```
