***HIRDLS [V4] Data Quality Document: on the NASA DISC [link on the AVDC]***

## Issues  Request

- Please keep the AVDC correlative data source
- active and updated.
- We will need this source of correlative data to validate new species as they improve.

## Slide 12

## Validation of high vertical resolution

- Mean difference, HIRDLS-COSMIC, for the Double COSMIC+HIRDLS coincidences. The solid line gives the difference, the outer dashed lines give the difference +/- the standard deviation of comparisons about the mean, and the inner dashed lines give the 1 standard deviation error bars of the mean.

**Mean Differences**

**Temperature comparison with COSMIC/GPS, **
**on small vertical distance scales.**

- _COINCIDENCE: Profiles were required to be within 0.75o great circle and 500 sec of each other_, giving 888 pairs.HIRDLS and COSMIC profiles were separately smoothed using a cosine bell filter of 2.8 km full width at half height (high pass filtered). The deviations from these profiles were then intercorrelated over the range 2.0 to 4.75 pressure scale height.

- J.J. Barnett

- The FORMOSAT-3/COSMIC constellation of six satellites,
- launched 14 April 2006, carries GPS receivers. Resolution = 1 km.
