Version 5.2.3 of SCC

A new SCC version (v5.2.3) has been released(18 /06/2021) in order to fix a bug affecting the calibration of Raman backscatter in lidar ratio profile , under specific conditions. In this version, only ELDA module has been upgraded from v3.4.7 to v3.4.8.

The bug could affect the calibration of backscatter profile of the lidar ratio product in case the maximum product height is set to a value which is lower with respect to the maximum height set for searching the calibration region.

The effect of this bug was that the backscatter profile delivered in lidar ratio product could be calibrated in a region above the maximum product height, i.e. in a region where the product is considered not fully reliable (while the backscatter profile delivered in the Raman/Elastic backscatter product types was not affected by this problem).

Considering the potential impact of this problem, it was decided to release this new SCC version with the bug fixed, even if the current one has been released just 40 days ago.

Version 5.2.1 of SCC

After the release of the SCC version 5.2, several feedback have been collected from you reporting some issues. So, a new SCC version (v5.2.1) has been released (10/03/2021) in which the following issues have been addressed:

Beside these fixed issues there is still one pending problem in the SCC v5.2.1 on which we are currently working on. This problem affects the CloudScreen module which sometime seems to misclassify strong dust events as cirrus cloud. Unfortunately this problem cannot be fixed quickly because we need to implement and test new criteria to be able to distinguish between these two cases. You will kept updated on that. In the meanwhile, if you noticed strong dust events which are not processed by the SCC because of this misclassification you could provide your manual cloudmask in the raw input file. Obviously this is not a solution but just a work around to be used until the new version of the CloudScreen will be available. Please, download the documentation on how to submit your manual cloudmask in your raw data file.

Version 5.2 of SCC

The new SCC version (released on 10/02/2021) brings many important updates and enhancements which are summarized in the SCC version 5.2 release notes

Major modifications regards:

Please note that the new CloudScreen module is more on conservative side with respect to the previous one. So in general it is possible that we come up with less products with respect to the past but hopefully more reliable in terms of cloud  screening.

In making the update we tried to not break any existing configuration. So you should be able to log-in with your old username and password and find on the server all the configurations and measurements you have already uploaded before the upgrade.

As a consequence all the products on the servers are still the ones generated by you running the previous SCC version (v5.1). If you like, you can re-calculate those products using the new version of the SCC. Please keep in mind that in this case you are going to overwrite all your products! So if you like to keep your old products you should make a back-up of them before trying to re-run the new SCC version.

Version 5.1.1 of SCC

The new SCC version (released on 06/06/2019) brings many important updates and enhancements:

 

1) SCC product file format

The SCC v5.1 generates products which are:

 

2) Quicklook web interface

A new color was adopted to distinguish between cloud-free regions (white regions) from no-data region (grey regions) in cloudmask quicklooks.

Please, keep in mind that the quicklook web interface (https://quicklooks.earlinet.org) will be password protected until the 31 of July 2019. After this date the password will be removed and it will become accessible to anybody.

IMPORTANT: We recommend to take advantage from this period for checking that everything is fine for your station on EARLINET quicklook web interface (https://quicklooks.earlinet.org).
In particular, you should check that:

 

3) Other enhancements

HHHHMMDDssshhmm

where 'sss' is the new 3 digits station code and HHHHMMDD hhmm is the start of the measurement.

In making the update we tried to not break any existing configuration.
So you should be able to log-in with your old username and password and find on the server all the configurations and measurements you have already uploaded before the upgrade.

As a consequence all the products on the servers are still the ones generated by you running the previous SCC version (v5.0). If you like you can re-calculate those products using the new version of the SCC (actually we recommend to do so). Please, keep in mind that in this case you are going to overwrite all your products! So, if you like to keep your old products you should make a back-up of them before trying to re-run the new SCC version.

Please, always remember that in order to generate the new products (HiRELPP, Cloumask, ELIC and ELQUICK), it is necessary to define for the configuration(s) an high resolution product, following some basic instructions on how to do that.

Version 5.0 of SCC

The new SCC version (released on 08/11/2018) brings many important updates and enhancements:

 

1) New SCC workflow

The SCC workflow has been modified by including 4 new calculus modules: HiRELPP, Cloudmask, ELIC and ELQUICK

 

2) SCC product file format

All the SCC products are in NetCDF format and are CF compliant. To meet the CF compliance we had to modify the NetCDF structure of all the SCC products with respect to the old ones. This means that your reading software for the SCC products should be changed accordingly.In particular, the optical products generated by the SCC v5.0 are different from the EARLINET files we have used up to now. The new format is the same we have used for the publication of the data on CERA database. For the moment such files CANNOT be uploaded on the EARLINET database because it still requires the old format. Anyway we are going to release the new version of EARLINET database (presumably in January 2019) that will accept the new format only.

IMPORTANT: only the SCC product file format is changed. The raw input file format is still the same. This means no specific modifications are needed in your own converter to generate input file for the new SCC version.

 

3) Other enhancements

Please, note that in order to generate the new products (HiRELPP, Cloumask, ELIC and ELQUICK), it is necessary to define for the configuration(s) an high resolution product, following some basic instructions on how to do that.
