  CSPP Sounder QuickLook (QL) Software for Display of HEAP NUCAPS, HSRTV, MiRS and IAPP Atmospheric Retrievals Version 1.4 Release

30 July 2026

Update to the CSPP software for plotting navigated sounder products derived from one of several CSPP software packages that create Environmental Data Record (EDR) and Level 2 atmospheric retrievals. It consists of Sounder QuickLook (QL) plotting scripts, which generate navigated pressure level two-dimensional (2D) plots of temperature and moisture, as well as Skew-T thermodynamic diagrams. Many options exist that allow users to customize the plots for a given region of interest.

The QL software supports the following CSPP package files:
  • CSPP Hyper-Spectral Enterprise Algorithm Package (HEAP) NOAA Unique Combined Processing System (NUCAPS) (CSPP HEAP NUCAPS Files),
  • CSPP Microwave Integrated Retrieval System (CSPP MiRS Files), and
  • CSPP Hyperspectral Sounder Retrievals (Dual Regression) (CSPP HSRTV Files).

In addition, the following product files are supported for archived historical data:

  • CSPP Hyper-Spectral Enterprise Algorithm Package (HEAP) NOAA Unique Combined Processing System (NUCAPS) (CSPP HEAP NUCAPS Aggregated Files). Please Note: CSPP HEAP no longer supports the creation of aggregated NUCAPS output files.
  • CSPP International ATOVS Processing Package (CSPP IAPP Files). Please Note: CSPP IAPP does not support any current active polar orbiting missions.
What is New in CSPP Sounder Quicklook Release Version 1.4?
  • Added NOAA-21 and Metop-C and Metop-B HEAP NUCAPS retrieval file support.
  • Added NOAA-21 CrIS HSRTV file support.
  • Added CAPE and Lifted Index stability parameters support.
  • Ability to better handle input files with varying granule lengths.
System Requirements
  • Intel or AMD CPU with 64-bit instruction support,
  • 1 GB RAM,
  • Rocky Linux 8.10. The software has also been tested on Rocky Linux 9 and WSL Ubuntu 22.04,
  • 3 GB of disk space (plus space for your own DB data and CSPP Sounder QL products).

The Sounder Quick Look plotting scripts include many options, allowing users to customize the output images. Users can define the image geographic boundaries, map projection, data range of the plot and map resolution. Other options include choosing to display a scatter plot, choosing the geographic center point of the image as well as the output .png image resolution in Dots-per-Inch (DPI).

Software, execution scripts and documentation are included with the release.
