# ncchecker(1)

netCDF Compliance Checker

## NAME

ncchecker - netCDF Compliance Checker

## SYNTAX

ncchecker \[-d *dbg\_lvl*\] \[-i *drc\_in*\] \[--tests= *tst\_lst*\] \[-x\] \[-v *var\_lst*\] \[--version \] *input-files*

## DESCRIPTION

**ncchecker** checks files for compliance with best practices rules and recommendations from various data and metadata standards bodies. These include the Climate & Forecast (CF) Metadata Conventions and the NASA Dataset Interoperability Working Group (DIWG) recommendations.  It reads  *input-files* from **stdin,** or the command, performs checks requested in the *tests* option, if any (otherwise it performs all tests), and writes the results to  **stdout.** Some standard **NCO** options are supported, including increasing the verbosity level with \[-D *dbg\_lvl*\], excluding variables with \[-x\] variable subsetting with \[-v *var\_lst*\], and printing the version with  \[--version\]. The output contains counts of the location and number of failed tests, or prints "SUCCESS" for tests with no failures.

If the **info** and **NCO** programs are properly installed at your site, the command

  **info nco**

should give you access to the complete manual, except for the TeX-intensive portions.
