Reimbursement Policy

If selected for travel support, reimbursement of travel expenses (airfare/ground transportation/per diem) to the maximum as awarded to you will require being compliant with NSF policies, EarthScope travel policies, and supplying proper documentation. A specific DAS RCN Field Experience reimbursement form will be sent to you to fill out and return with updated instructions.

Itemized receipts are required for out-of-pocket expenses as well as proper documentation. Specific instructions sent to selected participants will include:

• Airfare receipts should show the itinerary, itemization of cost, and class of airfare (NOTE: if using a foreign-flag air carrier, proper justification will be needed otherwise the expense may not be covered.)
• Mileage, if applicable, should be supported by a Google map showing the starting and ending location.
  • If driving more than 500 miles one direction:
    • A printout of a comparison, economy class airfare for the applicable dates of travel between the the nearest commercial airport serving the origin and destination cities is required.
    • Reimbursement will not exceed the lesser of the cost of per-mile reimbursement plus tolls or the comparison airfare plus transfer costs to and from the airport.
  • Gas purchases are not allowed as this is covered by mileage.
  • Any other transportation expenses, such as taxi cab/Uber/Lyft (to/from airport/hotel), parking, and tolls are allowable.  Receipts should include dates, amounts, and other relevant information.
• Rental cars are not reimbursable under this provided support.
