PRINCESS SIRINDHORN NEUTRON MONITOR AT DOI INTHANON, THAILAND Latitude 67.60 deg N, Longitude 62.90 deg E, Altitude 30 m Reference pressure 728 mmHg, Pressure coefficient 0.854%/mmHg Operated by Mahidol University, Chulalongkorn University, and Ubon Rajathanee University PRE-ARCHIVAL DATA (version 3.5): Start date: 2021 March 1 End date: 2021 March 31 Data prepared: 2021 April 08 CONDITIONS FOR USE OF DATA: You are welcome to use data from the Princess Sirindhorn Neutron Monitor at Doi Inthanon, Thailand, under the following conditions: 1. You agree to acknowledge the Princess Sirindhorn Neutron Monitor Project in any published use of the data. Example: "Neutron monitor data from Doi Inthanon were provided by courtesy of the Princess Sirindhorn Neutron Monitor Program." 2. You agree to send a copy of any publication or thesis using these data to: Prof. David Ruffolo Space Physics and Energetic Particles Group Department of Physics, Faculty of Science Mahidol University Bangkok, 10400, THAILAND e-mail: ruffolo.physics@gmail.com Scientific questions about the data may be addressed to Prof. Ruffolo. 3. You may share these data with colleagues, provided you inform them of these conditions. This is most simply accomplished by including the header information that came with the file when you got it. EXPLANATION OF THE DATA AND FORMAT: While these data are accurate to the best of our knowledge as of the date given above, we reserve the right to correct errors without notifying possible recipients of these data. Columns in the data are as follows: 1. Year 2. Day of year (1 for January 1, etc.) 3. Center of time interval, in UT 4. Neutron monitor counts per hour, corrected for pressure effect 5. Neutron monitor counts per hour, not corrected for pressure effect 6. Atmospheric pressure, in millimeters of mercury A zero in any data field denotes a data gap. A line containing 42 asterisks occurs immediately preceding and following the data, and nowhere else in this file. Software can use this line to seek past this header material.
