Dear Thakurdc,
Thank you for your interest in PRECIS.
The PRECIS software is provided freely to users from non-Annex II nations only in conjunction only after attending at a training workshop. The date for our next training workshop in UK is yet to be confirmed but if you wish I could put you on the waiting list. Alternatively you could let us know the exact needs of your research by emailing to
precis@metoffice.gov.uk and depending on your geographical location and research question, we may be able to put you in touch with some institute that may already have the data you are after. Note, if this is the case we can only ask but not demand!
Regards,
Saeed
