 v5 As different data policies and terms of use apply to the datasets stored at the ECOMS-UDG, a fine-grained user authorization scheme has been implemented, based on different access roles which are provided under request. For instance, while the CFSv2 reforecast (CFSRR) dataset is publicly available, the System4 reforecast is restricted to ECOMS partners. Thus, the role cfsrr is provided to all potential users, whereas the role system4 is limited to verified ECOMS partners. = Authorization scheme overview In order to obtain a user account, first [http://meteo.unican.es/tap/register register] at the THREDDS Administration Panel ('''TAP''') and fill in the required information (please, specify if you are involved in EUPORIAS, SPECS and/or NACLIM in the ''motivation'' field). As different data policies and terms of use apply to the datasets stored at the ECOMS-UDG, a fine-grained user authorization scheme has been implemented, based on different access roles which are provided under request. == Access to restricted datasets Dataset availability is a function of the group to which the applicant belongs to. Currently there are four groups defined. Three of them correspond to the different FP7 projects conforming ECOMS ('''EUPORIAS''', '''SPECS''' and '''NACLIM'''), and therefore applicants belonging to any of these groups can request an enrolment in the corresponding project(s) he/she is (officially) participating.' Enrolment in any of these 3 groups is subject to explicit approval by project leaders in each case, and therefore group acceptance is not immediate, and may take some time. Acceptance is always confirmed via email to the applicant. Membership to any of these three groups grants access to restricted datasets (ECMWF's System4 seasonal/annual forecasts). [[Image(2_registrationPanel.png,align=center,width=320px)]] == Access to public datasets A fourth group, ('''PUBLIC''') has open access characteristics, and therefore project membership is not required in this case. Thus, users external to ECOMS can also apply, being the access automatically given in this case. Currently, three public datasets are available in this group: WATCH Forcing Dataset ERA-Interim (gridded observations), NCEP-NCAR (reanalysis) and CFSv2 hindcast (seasonal forecast). In all cases, dataset access is conditioned to the acceptance of the particular usage terms and conditions. = Registration process In order to obtain a user account, first [http://meteo.unican.es/tap/register register] at the THREDDS Administration Panel ('''TAP''') and fill in the required information (please also specify the ''institution'' and ''intended usage'' fields). [[Image(3_registrationSuccessful.png, align=center,width=300px)]] Then, group acceptance roles can be requested from the ''My groups'' section of your home menu. An agreement window will show the terms of use of the data which must be accepted before saving. Then, roles can be requested from the ''My Enrolments'' in the [http://meteo.unican.es/tap TAP] from those currently available (e.g. ''cfsrr'' to access CFSv2 reforecast). An agreement window will show the terms of use of the data which must be accepted before saving. [[Image(4_roleEditing.png, align=center,width=420px)]] After saving, the automatic roles (e.g. ''cfsrr'')  will be automatically assigned, whereas the restricted roles (e.g. ''System4'') will be moderated by the administrator, so the decision of acceptance (or rejection) will be sent by email  in the following days.
